Detroit Lions at Indianapolis Colts
Saturday, August 29, 2026
1:00 PM ET, Lucas Oil Stadium
Saturday afternoon’s preseason finale at Lucas Oil Stadium has significant line movement pointing squarely at the home team, and the situational factors backing it up make this one of the cleaner plays on the Week 3 board.
The Colts are 3.5-point home favorites over the Lions with a total of 36.5. This game opened with Indianapolis as a 1.5-point favorite. Since then, sharp money has moved the spread a full two points toward the Colts. That kind of movement in a preseason game reflects the market catching up to information about how each team is approaching the finale, and both head coaches have publicly confirmed exactly why the market has shifted.
Let’s start with the coaching plans.
Shane Steichen has laid out a specific and confirmed rotation for his Colts. Anthony Richardson starts and plays the entire first quarter with many of Indianapolis’s starters, who are expected to play between 8 and 12 snaps. Riley Leonard takes over in the second quarter. Easton Stick finishes the game. Daniel Jones — who was named the Colts’ starting quarterback for the 2026 regular season — will not play. That’s the head coach committing to giving his key veterans meaningful first-quarter reps to build regular season rhythm before shutting them down for the rest of the game.
On the Detroit sideline, Dan Campbell is doing the opposite. Jared Goff will not play. Neither will any of the other Lions starters. Detroit has been extremely consistent about this approach throughout the Campbell era — the preseason finale is treated as an evaluation game for backups and roster-bubble players only. Josh Dobbs and undrafted rookie Luke Altmyer will continue splitting reps as they compete for the backup quarterback job, with Dobbs coming off a 50-yard touchdown run last week that reminded everyone he can still make plays.
That creates a fundamental asymmetry in the first quarter. Indianapolis starters against Detroit backups is a talent mismatch that shows up on the scoreboard. Anthony Richardson isn’t going to be careful and conservative — he’s going to be looking to build chemistry with Michael Pittman Jr., Josh Downs, and Alec Pierce, and he’s going to be running the offense at real NFL speed. The Lions will be starting Josh Dobbs or Luke Altmyer against Indianapolis’s first-team defense.
Once Richardson exits after the first quarter, the game becomes an evaluation exercise for both sides. But the damage is likely done by then. If Indianapolis builds a 10-3 or 14-3 lead in the first quarter, their backup rotation only needs to hold serve against Detroit’s backup rotation to cover the number.
The Colts have real motivation heading into this game. They finished 2025 by allowing games to slip away late — their 61.3 passer rating in the fourth quarter was the lowest in the entire NFL. That’s a full-year stat that hasn’t fully resolved as the team enters the regular season, and Steichen has been emphasizing early-game execution as an offseason priority. Steichen wants his starters to prove they can start fast, and Saturday’s first quarter is the last chance to see that before the regular season opens.
Detroit’s approach makes sense from a roster-preservation standpoint — Campbell has playoff expectations for his team and doesn’t want to risk injury to any starter. But that approach has consistently produced poor preseason finale results. Detroit is averaging 15.5 points per game this preseason, and against a Colts defense that has been solid despite the 0-1-1 record, that scoring pace isn’t going to be enough to keep up with an Indianapolis team playing starters early.
The 3.5-point spread makes sense given the coaching asymmetry, and the movement from -1.5 to -3.5 tells you sharp money has been reading it the same way. Getting a home team laying under a touchdown when they’re the only team playing starters is exactly the kind of value spot to target.
I looked at the total too. The 36.5 is defensible given both teams are running backup rotations for most of the game, and Detroit’s approach isn’t likely to produce big second-half scoring. There’s a case for the Under. But the side offers the clearer signal given the confirmed coaching plans.
The Pick: Indianapolis Colts -3.5
