Bash is back with a deep dive into the WCC’s premier rivalry. With Gonzaga laying nearly ten points, this best bet focuses on whether the Gaels’ perimeter defense can hold up against Braden Huff and Graham Ike.
The Setup: Saint Mary’s at Gonzaga
Gonzaga’s laying 9.5 points at home against Saint Mary’s on Saturday night, and this is one of those lines that looks perfectly reasonable until you start digging into what’s actually happening on the floor. Both teams roll in at 9-1, both teams are playing elite defense, and both teams have legitimate national tournament aspirations. So why is the spread sitting at nearly double digits?
The answer lives in the efficiency numbers, and it’s stark. According to collegebasketballdata.com, Gonzaga owns the second-ranked adjusted defensive efficiency in the country at 88.5, paired with a 13th-ranked adjusted offense at 122.4. That’s a net rating of 33.9, good for second nationally. Saint Mary’s? They’re no slouch at 19th overall with a net rating of 19.8, but when you’re giving up nearly 15 points per 100 possessions more than Gonzaga in adjusted efficiency, the market’s going to make you pay for it. This spread isn’t about disrespecting the Gaels—it’s about acknowledging that Gonzaga’s operating on a different level right now, especially at McCarthey Athletic Center where they’ve been absolutely suffocating teams.

Why This Number Makes Sense (or Doesn’t)
Let’s talk tempo first, because it matters here more than people realize. Saint Mary’s plays at a 53.9 pace—that’s 365th in the country. They’re the ultimate grind-it-out team. Gonzaga, meanwhile, runs at 74.6 possessions per game, ranked 19th nationally. That’s a 20-possession differential, which is massive when you’re trying to project a final score.
Here’s where it gets interesting: when you force this game into Saint Mary’s preferred tempo, you’re naturally suppressing the total number of possessions, which theoretically should keep the game closer. But Gonzaga’s defensive rating of 87.5 (4th nationally) suggests they’re elite regardless of pace. They’re holding opponents to just 37.1% from the field (10th in the country) and 26.8% from three (17th nationally). The Zags don’t need 80 possessions to pull away—they can win ugly if they have to.
The total sitting at 145.5 feels about right given Saint Mary’s glacial pace. But the spread at 9.5? That’s the market saying Gonzaga’s efficiency advantage is so pronounced that even in a rock fight, they’ll find separation. When you’re talking about a 14.1-point gap in adjusted net efficiency between these teams, a 9.5-point spread at home isn’t aggressive—it’s mathematical.
Saint Mary’s Breakdown: The Analytical Edge
The Gaels do two things exceptionally well: they defend the hell out of you, and they don’t beat themselves. Their 97.3 adjusted defensive efficiency ranks 23rd nationally, and they’re holding opponents to just 37.8% from the field (17th) and 28.4% from three (38th). That 63.5 points allowed per game ranks 15th in the country. This is a team built on making you uncomfortable.
Offensively, Saint Mary’s is more efficient than you’d think. Their 117.1 adjusted offensive efficiency ranks 40th nationally, and they’re shooting 39.7% from three (18th in the country). Paulius Murauskas leads the way at 18.0 points per game, while Mikey Lewis adds 16.8. Joshua Dent’s playmaking (4.8 assists per game, 92nd nationally) is the engine that makes this offense hum. They’re not flashy, but with a 150.3 offensive rating and 60.4% true shooting percentage, they’re dangerous when they get into their rhythm.
The problem? That 53.9 pace means fewer possessions to exploit any advantages they might create. And their turnover ratio of 0.2 (343rd nationally) suggests they’re not generating the extra opportunities that could help them keep pace with a team as efficient as Gonzaga.
Gonzaga Breakdown: The Counterpoint
Gonzaga’s not just good—they’re operating at an elite level on both ends. That 88.5 adjusted defensive efficiency (2nd nationally) is the foundation, but the offense is humming too. They’re scoring 92.9 points per game (11th nationally) while shooting 52.2% from the field (13th) and assisting on 20.4 baskets per game (6th). This is a complete basketball team.
Braden Huff (17.0 PPG) and Graham Ike (16.4 PPG, 8.1 RPG) give them a formidable frontcourt, but the real separator is their ability to dominate the glass. At 44.8 rebounds per game (5th nationally), they’re controlling possessions on both ends. They’re generating 9.3 steals per game (40th) and turning defense into offense with 156 fast break points on the season.
The turnover ratio of 0.1 (17th nationally) tells you they’re disciplined, and their 74.6 pace means they’re dictating tempo without sacrificing efficiency. When you combine that pace advantage with their defensive suffocation, you’ve got a team that can win games multiple ways. They’re not one-dimensional, and that’s why this spread makes sense.
The Matchup: Where This Gets Decided
This game comes down to one simple question: can Saint Mary’s force Gonzaga into the mud, or will the Zags impose their will and create enough possessions to pull away?
Saint Mary’s wants this game in the low 60s possession-wise. They need to control tempo, limit transition opportunities, and force Gonzaga into half-court sets where their 23rd-ranked adjusted defense can make life difficult. The problem is Gonzaga’s defensive rating suggests they’re perfectly comfortable winning 65-58. They don’t need to run to be effective.
The rebounding battle matters here. Gonzaga’s 44.8 boards per game (5th nationally) against Saint Mary’s 41.1 (46th) gives the Zags a clear edge. If Gonzaga’s controlling the glass, they’re getting extra possessions even in a slower game, and that’s death for Saint Mary’s. Andrew McKeever’s 10.7 rebounds per game (12th nationally) will be tested, and he’ll need to be dominant to keep this competitive.
The other factor? Three-point shooting. Saint Mary’s is hitting 39.7% from deep, but Gonzaga’s allowing just 26.8% from three. If the Gaels can’t get clean looks from distance, their offensive efficiency craters. And with Gonzaga’s perimeter defense ranking 17th nationally, those clean looks won’t come easy.
Bash’s Best Bet
I’m on Gonzaga -9.5. Look, I get the hesitation. Same records, rivalry game, Saint Mary’s defense is legit. But the efficiency gap here is too wide to ignore. Gonzaga’s 14-point advantage in adjusted net efficiency isn’t noise—it’s signal. They’re better on both ends, they control the glass, and they’re at home where they’ve been absolutely dominant.
Saint Mary’s will slow this game down and keep it ugly for stretches, but ugly doesn’t mean close. Gonzaga’s proven they can win at any pace, and their defensive rating suggests they’re not giving up easy buckets regardless of tempo. The Zags win this one 78-65, and we cash the double-digit spread with room to spare. Lay the points.
