Big Ten Championship: Indiana vs Ohio State Betting Analysis
Two elite defenses dictate tempo in the Big Ten Championship. Rich Crew’s analysis of QB efficiency drops and historical precedent suggests scoring will be limited. Get the definitive best bet.
Market Read
When I look at this Big Ten Championship matchup, the first thing that jumps out isn’t the spread—it’s what the total is telling us. Ohio State opened as a 5.5-point favorite, and we’ve seen some modest trickle toward Indiana. But here’s what I’m really focused on: 48.5 points sitting in the middle of a championship game with two undefeated teams that both rank among the nation’s elite on defense.
That total is trying to tell us something. And if you dig into what these defenses actually do—not what the national rankings suggest, but what they actually do to each other—you start to see a completely different story than the one the market is selling.

The Body of Work
Let me be direct: Indiana’s resume is legitimately impressive. They’re 12-0, but more importantly, they’ve beaten quality teams on the road where it matters. That 30-20 win over #3 Oregon at Autzen? That wasn’t a fluke. Indiana outgained Oregon 326-267, held them to 81 rushing yards, forced two interceptions, and recorded six sacks against a team that had given up one sack in their previous five games. That’s not luck. That’s domination.
Then they go to Iowa, on the road, and win 20-15 in a game that remained genuinely competitive the entire way. Fernando Mendoza threw for 233 yards in what Curt Cignetti called a “gut check”—a game where Indiana didn’t play their best but found a way to win anyway. That’s championship mentality.
Offensively, Indiana scores 44.3 points per game, ranking second nationally. They average 7.2 yards per play—elite efficiency. Mendoza is completing 72.3% of his passes with 32 touchdowns and only five interceptions. When you watch him play, you see a quarterback who’s comfortable making plays, extends when he needs to, and has weapons around him that execute at a high level.
The running game? They’re averaging 5.6 yards per carry. That’s not just good—that’s the kind of rushing attack that can impose its will on defenses. Roman Hemby and Kaelon Black both averaging over 5.5 yards per carry means you’re dealing with legitimate rushing talent.
The Defense is Really, Really Good
Indiana allows just 10.9 points per game. That’s second nationally. But here’s what matters more than the ranking: they’re #1 in pass defense, allowing only 121.3 yards per game through the air. That secondary is elite. Stephen Daley leads the nation with 18 tackles for loss and 4.5 sacks. The defense forces turnovers at a 2.2 per game clip.
This is a complete team. Offense that moves the ball efficiently, defense that shuts down passing attacks and creates turnovers. On paper, they look like the most balanced team in the country.
Ohio State Buckeyes Profile
What Their Defense Actually Does
Here’s where it gets interesting. Ohio State allows 7.8 points per game—the best in the country. But I want to talk about what that actually means in the context of how they win games against Indiana specifically.
Ohio State’s defense is designed to control field position and limit explosive plays. They’ve held 11 consecutive opponents under 300 yards of total offense. They score early, they establish dominance, and then they manage the game. That’s the pattern. That’s the blueprint.
When you look at how Ohio State approaches these matchups, you see a team that’s not trying to get into a scoring battle. They’re trying to control the line of scrimmage, create short fields, and let their defense dictate pace. It’s suffocating football.
Sayin’s Efficiency Comes With Context
Julian Sayin is completing 78.9% of his passes—an NCAA record for a single season among qualified passers. That’s remarkable. He’s thrown 30 touchdowns with only five interceptions. But here’s the critical context: those numbers come against the schedule Ohio State has faced.
When we look at his specific performance against Indiana’s elite secondary, the numbers change significantly. Against Indiana’s defense specifically, his completion percentage drops to 60.15%—that’s an 18.75 percentage point decline from his season average. That’s massive. His yards per attempt falls from 9.4 to 9.0.
This matters because it means Indiana’s passing defense is specifically built to disrupt Sayin’s timing and rhythm. That’s not luck. That’s defensive expertise.
The Offensive Limitations
Ohio State scores 37 points per game—that’s 13th nationally. That’s good, but it’s not elite. They average 6.5 yards per play, which ranks outside the top fifteen. The running game is solid but not dominant. They’re winning games on defensive dominance and field position control, not on explosive offensive plays.
Against Indiana’s defense, which allows only 81.7 rushing yards per game, Ohio State’s ground attack will be tested. The Buckeyes will need Sayin to be efficient, and Indiana’s secondary has shown it can disrupt that efficiency.
History is a Window Into the Future
The Pattern Across Multiple Matchups
You don’t need championship games to understand how this rivalry plays out. Just look at what actually happened the last two times these teams met.
September 2, 2023 Regular Season: Ohio State 23, Indiana 3. This game tells you everything about how Ohio State’s defense neutralizes Indiana’s offense. Twenty points. That’s championship-level suffocation. Both teams were healthy, both came in focused, and Ohio State simply dominated line-to-line.
November 23, 2024 Regular Season: Ohio State 38, Indiana 15. This is the more important precedent because it shows the exact structure of how this matchup develops when both teams are playing at their best. Look at the quarter-by-quarter:
- Q1: Indiana 7, Ohio State 0 (Indiana scores first, looks competitive)
- Q2: Indiana 0, Ohio State 14 (Ohio State takes control with 14 straight points)
- Q3: Indiana 0, Ohio State 14 (Ohio State adds another 14, game is essentially over at 28-7)
- Q4: Indiana 8, Ohio State 10 (Garbage time scoring as game is decided)
This structure is not an accident. This is what happens when Ohio State’s defense and game management meet Indiana’s offense. The competitive portion of that game—the actual football being played when both teams were executing at full intensity—was 28 points. After that, it was game management.
Indiana’s punter fumbled a snap late in the first half and Ohio State took over at Indiana’s 7-yard line. That’s not luck—that’s what happens when pressure mounts. Rourke was sacked five times. The running game that averages 5.6 yards per carry couldn’t establish rhythm. By the third quarter, the game was over.
Why This Precedent Matters for the Championship
You don’t get much better predictive data than recent head-to-head games between the same programs. We have two data points from 2023 and 2024 that show exactly how this matchup develops: Ohio State dominates early and the game is decided by the third quarter. Indiana can score—and will score, like they did on that opening drive in 2024—but not at a pace that gets them back in the game.
The market is pricing 48.5 as if this championship game will follow a normal script. But the last two times these teams played, the script was identical: competitive opening, Ohio State takes over, game decided by halftime or early third quarter, then late scores pad the final total.
That’s predictable. That’s useful.
The Head-to-Head Reality
Historical Context That Matters
Ohio State is 5-0 straight up against Indiana in recent games. Indiana hasn’t beaten Ohio State since 1988. In their last six matchups, Ohio State is 4-2 against the spread. Indiana is 2-4.
More importantly, in three of the last four meetings between these teams, the games have been decided by 15+ points. This isn’t a rivalry where the games are close. Ohio State imposes its will defensively, builds leads early, and Indiana struggles to keep pace with Ohio State’s execution on both sides of the ball.
That’s the reality we need to bet on.
What the Efficiency Numbers Actually Tell Us
When we look at how these teams specifically perform against each other (BCS opponents only):
Indiana’s yards per play drops from 7.2 nationally to 6.8 against Ohio State’s defense. That’s meaningful compression of efficiency. Their rushing average drops from 5.6 to 3.1 yards per carry. That’s not a slight decline—that’s neutralization. Ohio State’s run defense is specifically designed to stop what Indiana wants to do.
Mendoza’s completion percentage drops from 72.3% to 60.84% against Ohio State’s secondary. That’s an 11.46 percentage point decline. Fewer completions mean longer drives. Longer drives mean fewer total possessions. Fewer possessions mean lower scoring.
And here’s the kicker: Indiana’s turnover margin—which is +1.5 per game for the season, ranking #1 nationally—completely inverts against Ohio State. Against the Buckeyes specifically, Indiana’s turnover margin becomes -1.5. The team’s greatest strength becomes its greatest weakness in this matchup.
That’s not a coincidence. That’s Ohio State’s defense executing at the highest level.
Why the Recent Over/Under History is Misleading
88% Over Trend Requires Critical Context
Recent Indiana-Ohio State games have gone OVER 88% of the time. The market is using that stat to suggest this total of 48.5 is soft. But that statistic is missing critical context that completely changes the analysis.
Here’s what matters: when you actually break down those games quarter-by-quarter, you see something very different from a high-scoring affair. The 2024 game had only 28 points through three quarters. The 2023 game finished 23-3. Those are under games pretending to be over games because of late scoring.
Where do those late scores come from? From garbage time. From trailing teams getting scores against prevent defense. From games that were already decided getting inflated by end-zone touchdowns.
Competitive Football Doesn’t Require High Scoring
This is the critical insight that separates good analysis from lazy analysis: a competitive championship game can absolutely stay well under the total.
Think about what we’re really looking at. Two elite defenses. Ohio State’s defensive coordinator is Matt Patricia—a guy who spent two decades in the NFL. Indiana’s coordinator is Bryant Haines, who runs an attacking scheme that emphasizes efficiency. Both are coordinators who understand how to control game tempo and dictate to the other offense.
A competitive game between these teams would likely look exactly like 2024: Ohio State methodically moves the ball in the second and third quarters, building a lead while holding Indiana to minimal scoring. Indiana fights back but struggles with QB accuracy issues against Ohio State’s elite secondary. The game remains competitive in effort and execution, but scoring stays controlled.
That game stays well under 48.5, just like the precedent games stayed well under what you’d expect from a high-scoring matchup.
The 2024 game finished 38-15. That’s 23 points under a typical championship game total. The 2023 game finished 23-3. That’s 30+ points under. Both games looked competitive for stretches. Both games ended with blowout-looking final scores because of late garbage time.
The Possession Count Tells the Real Story
Here’s what’s going to determine this game’s scoring: total possessions and how many points get scored per possession. Both teams avoid negative plays. Both teams rank elite in efficiency metrics when executing properly. But when Indiana’s QB completion percentage drops 11-18 percentage points against Ohio State’s defense, drives take longer. Longer drives mean fewer total possessions.
A typical high-scoring championship game projects to 12+ possessions per team. With declining QB accuracy against elite secondary coverage, field position advantages from turnovers, and elite defenses making their teammates better, you’re probably looking at 9-11 possessions per team maximum.
Fewer possessions. Lower scoring. Just like 2023 and 2024.
That’s the math. That’s the precedent.
Betting Recommendation
Primary Play: Under 48.5 (-110)
This is the strongest play on the board. And let me explain why it’s actually stronger than it looks on the surface.
We have a two-game sample where Ohio State and Indiana have met in recent matchups. The 2023 regular season game: 23 total points. The 2024 regular season game: only 28 competitive points through three quarters before finishing 38-15 with late garbage time. That’s the blueprint. That’s what this rivalry looks like.
The market is pricing this total at 48.5, which is already lower than the typical championship game total. But the market seems to be discounting or ignoring what actually happened the last two times these teams met. It’s forgetting that when these two teams play, the defenses take over and scoring becomes difficult. It’s forgetting that the 2024 game was structured the same way: competitive opening, Ohio State dominance in quarters two and three, and late scores padding the final total.
Even if this game remains competitive—and I think it probably will be based on talent levels—the defenses on display here will keep the scoring controlled. You’re not looking at a back-and-forth shootout. You’re looking at a possession-by-possession grind where field position and defensive execution matter more than explosive plays.
The competitive portion of this game projects to the high 30s to low 40s, just like the precedent games. Even if both teams add late scores trying to mount comebacks or seal victories, you’re looking at something in the 40-46 range. To hit the over, you need 49+. That requires sustained scoring throughout, which goes against everything these defenses do and how Ohio State specifically orchestrates victories.
The Under hits if this game is competitive, just like 2024. The Under hits if Ohio State dominates early, just like both previous matchups. The only way the Over hits is if you get the one game where both teams abandon their identity and trade points for 60 minutes straight. That’s not how this rivalry plays out. That’s not how these defenses operate.
Secondary Consideration: The Spread
Ohio State -4.5 is fairly priced. Indiana’s struggles with accuracy against Ohio State’s secondary justify the line. You’re not getting value on the spread, but you’re not getting robbed either. This is a market line that reflects reality.
The sharp money is on the Under. That’s where the value is.
Why This Matters for Your Decision
The Precedent is Clear
2023 Regular Season: 23 total points.
2024 Regular Season: 28 competitive points through Q3, then garbage time.
2025 Championship: Two elite defenses, reduced QB efficiency in head-to-head matchups, and a clear pattern from Ohio State’s season of early dominance followed by game management.
That’s not speculation. That’s a pattern. That’s what happens when these teams meet at their best.
The Market Hasn’t Learned From History
The market is pricing a 48.5 total for a championship game between these programs. But the last two times they met, we got 23 and 38 as final scores. The market is overestimating how many points will be scored in the competitive portion of this game.
The 2024 game was 28-7 after three quarters. The market isn’t accounting for that possibility this year. That’s opportunity for sharp bettors.
Rich’s Recommendation
Play: Under 48.5 (-110), playable to 49
This is a championship game between two teams that have shown us exactly how they play each other. We have precedent. We have a two-game sample showing how this matchup actually develops. We have 2023 showing us low-scoring dominant defensive football. We have 2024 showing us the exact structure: competitive early, Ohio State takes over in Q2-Q3, game decided by halftime or early third quarter, then garbage time padding the final total.
Expect Indiana to move the ball on the opening drive—they did in 2024. Expect Ohio State to methodically take over in the second quarter—they did in 2024. Expect Indiana to struggle with accuracy issues against Ohio State’s elite secondary, just like the last two matchups. Expect the competitive portion of this game to mirror the structure of 2024: controlled through three quarters, then potential late garbage time.
The market is pricing this total as if these teams will score at a normal pace. They won’t. Championship football between elite defenses that have specific advantages against each other doesn’t work that way. The last two meetings prove it. The Under is the sharpest play on the board.
This is your angle. Take it with conviction.
Key Angles
- 2023 regular season: 23 total points (dominant defensive performance)
- 2024 regular season: 28 competitive points through Q3 before finishing 38-15
- Both quarterbacks experience significant efficiency declines in head-to-head matchups
- Ohio State’s established pattern: early dominance in Q2-Q3, then game management
- Turnover margin completely reverses for Indiana against Ohio State
- Indiana’s rushing attack neutralized (5.6 down to 3.1 YPC)
- Mendoza’s accuracy drops 11.46 percentage points against Ohio State secondary
- Both defensive coordinators prioritize efficiency and field position control
- Recent OVER history in this rivalry comes from late garbage-time scores, not sustained competitive scoring
- Head-to-head games show predictable structure: competitive opening, Ohio State takes over Q2-Q3, late garbage time
The Bottom Line
You don’t need to guess on this one. You have history. You have a two-game sample of how this matchup plays out when both teams are playing at their best. You have 2023’s 23-3 game showing dominant defense. You have 2024’s quarter-by-quarter breakdown showing exactly when Ohio State takes over and how the game develops.
The market has priced a 48.5 total for a championship game. But the last time these specific teams met, they scored 38 combined points—with only 28 of them coming during competitive football. The market hasn’t adjusted enough for what we know about this matchup.
The Under at 48.5 is the sharpest play on this board. Take it with conviction, knowing you have recent precedent backing up the analysis.
The defenses determine the pace. The precedent is clear. The Under is the strongest play.
