South Dakota vs Boise State Prediction & Odds (Sep 19)

Four Touchdowns Is a Lot to Ask at Midnight

One team is 3-0 and has a quarterback completing 70 percent of his throws with 11 touchdowns against one interception. The other is 1-1 and is being asked to win by 29 points. That is the tension in South Dakota vs Boise State, kicking off Saturday, September 19, 2026 at 10:00 PM ET at Albertsons Stadium. The favorite is almost certainly the better team. The question a bettor has to answer is different: is the better team 28.5 points better?

The Matchup

As of today, the South Dakota Coyotes are 3-0 and sit 3rd of 9 in the Missouri Valley Football Conference. The Boise State Broncos are 1-1 and sit 2nd of 8 in the Pac-12 Conference. No season series or prior meeting data is provided here, so we are judging this one on the profiles in front of us. Boise State vs South Dakota is a Week 3 non-conference game in a hostile late-night environment, and the roster gap in size, depth and recruiting is real. But the Coyotes arrive unbeaten and playing clean football, and blowouts require a favorite to keep its foot down for four quarters.

Players to Watch

Austyn Modrzewski is the story. He is 46 of 66 for 727 yards with 11 touchdowns and 1 interception. That is 11.0 yards per attempt and a touchdown on roughly one of every six throws. Offenses that hit big plays and do not turn the ball over are exactly the ones that hang around on the scoreboard. For Boise State, Maddux Madsen is 32 of 57 for 402 yards and 4 touchdowns. Efficient, not explosive, and 57 attempts over two games suggests a team that leans on structure rather than volume passing. A methodical favorite is a favorite that can win comfortably without ever covering.

The Numbers

The point spread is the handicap. South Dakota +28.5 means the Coyotes can lose by up to 28 and the ticket still wins; they also win it outright if they pull the upset. A 29-point loss loses it. There is no push at a half point, so no ties and no refunds. Best price on that side is -105 at Hard Rock Bet, meaning a $100 bet profits $95.24 when it wins and loses $100 when it does not.

Break-even is 51.2 percent, the win rate you need just to stay flat. Boise State -28.5 wins only by 29 or more; a 28-point win loses. Best price is -102 at DraftKings, where a $100 bet profits $98.04 and break-even is 50.5 percent. The total is 59.5 combined points. Over 59.5 is +100 at theScore Bet, where $100 profits $100.00 and break-even is 50 percent, the lowest break-even in this market. Under 59.5 is -110 at Hard Rock Bet, $100 profits $90.91, break-even 52.4 percent.

Where the Value Is

Strip the bookmaker's built-in margin out and you get the market-implied probabilities. The Coyotes' cover chance at this line is 49.5 percent for Boise State and 50.5 percent for South Dakota. Note that is a cover number, not a win number, and the two are different questions. At -105, South Dakota +28.5 returns minus $1.40 per $100 risked; fair price for 50.5 percent is about -102.

Boise State -28.5 at -102 returns minus $1.97 per $100 risked. Over 59.5 at +100 is minus $3.20 per $100 risked, Under 59.5 at -110 is minus $1.49 per $100 risked. Every side here is priced slightly worse than the market's own read, so nothing is a mathematical edge. The smallest leak, and the side our read of the matchup agrees with, is the dog.

The Pick

South Dakota +28.5 at -105 (Hard Rock Bet). This is a matchup lean, not an edge play: the spread's own break-even is 51.2 percent and the no-vig cover number is 50.5 percent, so the price is not paying us what the market itself implies. We like it because a 70-percent-completion quarterback with an 11-to-1 touchdown-to-interception ratio is the type that keeps games from turning into 45-point routs, and because Boise State's passing profile reads efficient rather than explosive. If another book posts +29 or better at a similar price, take the bigger number; an extra half point on a dog only helps.

The Prediction

Boise State 34, South Dakota 13. That is 47 combined points, which lands under the total of 59.5, and a 21-point margin, which would cover the +28.5. The Broncos control the game and never need a fourth-quarter push. That is our read on this number; the Desk posts a documented free play on days like this one, and it sits right below.
