San Diego State vs Colorado State Prediction, Picks & Odds For October 24, 2026

Fifty-nine points. Then 56. Then 66, and that last total came in just three quarters. Colorado State’s defense has collapsed so completely that the Rams now rank dead last in the nation in total defense, nearly 50 yards per game worse than the next-closest team.

Jim Mora has already removed one defensive coordinator mid-game, and the interim play-caller just watched Texas State run for a school-record 503 yards. Now comes San Diego State, a risk-averse team that won’t be confused with the old Air Coryell attacks, but one that might be more dangerous with a freshman quarterback under center.

Our San Diego State vs Colorado State prediction breaks down the line movement, the quarterback questions and why the Rams are an awfully chancy investment right now. For more free college football picks, browse our full slate before kickoff.

San Diego State vs Colorado State Key Matchups and Handicap

Colorado State Defense Hits Rock Bottom

Colorado State’s defense continues to plumb new depths. The Rams have allowed 59, 56 and 66 points in their last three games and now rank dead last nationally in total defense, a staggering nearly 50 yards per game worse than the next-closest team, West Virginia.

Last week’s loss at Texas State was the latest embarrassment, as GJ Kinne’s Bobcats channeled Tom Osborne’s old Nebraska teams and piled up a school-record 503 rushing yards.

Colorado State Coordinator Carousel

The search for Jim Mora’s next defensive coordinator has reportedly attracted only a few rodeo clowns, test pilots and other risk-takers. Mora removed Tyson Summers from the role mid-game a few weeks ago against Oregon State, and defensive line coach Kenny McClendon took over play-calling duties at Texas State.

After surrendering 66 points in three quarters, McClendon is reportedly contemplating witness protection, and some are even calling for basketball coach Ali Farokmanesh to give it a try. Rumors of discontent in the locker room only add to the turmoil.

CSU Offense Still Producing With K’Saan Farrar

Offense has not been the problem in Fort Collins. Backup QB K’Saan Farrar, who followed Mora from UConn in the offseason, has generated ample horsepower in recent games. There is also word that early-season starter and Oklahoma State transfer Hauss Henjy may finally be ready to return from the hamstring injury that has sidelined him since mid-September. Either way, the Rams should be able to put points on the board.

San Diego State’s Conservative Attack

One possible saving grace for Colorado State is the visit from risk-averse San Diego State, which will not be mistaken for the Air Coryell attacks that first made the Aztecs famous. It is also worth noting that the teams that recently bombed the Rams, UTSA, Oregon State and Texas State, all have considerably more firepower than San Diego State.

Aztecs Quarterback Change Could Help

QB Jayden Denegal is questionable with an ankle injury that forced him out of last week’s game against Fresno State. That might actually be a plus for head coach Sean Lewis, as freshman Stone Sanders offers a bit more of an aerial threat.

Sanders helped the Aztecs pull out a 26-23 win to stay on the fringe of the new Pac-12 race and keep bowl hopes alive. Against the worst defense in the country, a quarterback willing to push the ball downfield could find plenty of success, even in his first college start.

San Diego State vs Colorado State ATS and Total Picks

San Diego State -1.5 Spread Pick

The degree of dysfunction on Colorado State’s defense, combined with rumors of locker room discontent, makes the Rams an awfully chancy investment. San Diego State may not have the firepower of the teams that recently torched Colorado State, but it does not need to.

The Aztecs simply need to win the game, and Sanders could give their offense an extra dimension. With the spread down to 1.5, laying the short number with San Diego State is nearly the same as taking the moneyline, and both are worth backing.

• Pick: San Diego State -1.5 (-102)

SDSU vs CSU Over Pick

Colorado State has allowed at least 56 points in three straight games, and its offense has continued to produce with Farrar under center. San Diego State’s attack is conservative by nature, but a freshman quarterback with more of an aerial threat facing the nation’s worst defense is a recipe for points. The over has attracted every tracked bet, and the matchup supports it.

• Pick: Over 62.5 (-112)

San Diego State vs Colorado State Best Bets

• Best Bet: San Diego State -1.5 (-102)
• Moneyline: San Diego State to win outright
• Total: Over 62.5 (-112)

The top play is San Diego State laying 1.5 points. Colorado State’s defense is in free fall, its coaching staff is scrambling and the locker room appears unsettled. The San Diego State moneyline backs the same handicap at a near-identical number, while Colorado State’s productive offense and historically bad defense make the over a strong complement.

Final Score Prediction for San Diego State vs Colorado State

Colorado State’s offense keeps the Rams in the game, but its defense cannot get enough stops. San Diego State takes advantage with a few more chances through the air and a steady ground game, and the Aztecs pull away late to keep their bowl hopes alive.

• Projected Final Score: San Diego State 35, Colorado State 31
• Moneyline: San Diego State wins outright
• Spread: San Diego State -1.5 (-102) covers
• Total: Over 62.5 (-112) cashes with 66 combined points
