Western Michigan vs Michigan State prediction and analysis

Overview of the Matchup

Friday night at Spartan Stadium, the Western Michigan Broncos visit the Michigan State Spartans in a non-conference college football opener. The Spartans come in as heavy favorites with a -20.5 point spread and an Over/Under set around 49.5 points, a testament to the expected dominance by Michigan State and a presumed defensive slog. This game pits a mid-tier Mid-American Conference team against a rebuilding Big Ten program aiming to reverse recent struggles.

Western Michigan Broncos Outlook

• The Broncos finished 6-7 last season under third-year head coach Lance Taylor, outperforming predictions slightly but fading late with losses in four of their last five contests.
• They hold a 5-3 record in MAC play from 2024 but are again predicted to finish near the bottom of their conference in 2025.
• Offensively, continuity is apparent with Walt Bell back as offensive coordinator, while defensively a new coordinator, Chris O’Leary, aims to improve a unit that could face challenges adapting.
• On the road against non-conference foes, Western Michigan has struggled historically, losing their last eight games, suggesting difficulty overcoming home crowd noise and quality opposition.

Michigan State Spartans Outlook

• The Spartans endured a disappointing 5-7 overall and 3-6 in Big Ten play last year, missing a bowl game for a third consecutive season.
• Second-year head coach Jonathan Smith returns with both coordinators retained, heralding stability on the sidelines.
• Quarterback Aidan Chiles returns after completing 59% of his passes with 13 touchdowns last season but must reduce turnovers significantly (he had 11 interceptions and 4 fumbles in 2024) to enable offensive progression.
• The offensive line presents a key concern: only one returning starter opens questions about early cohesion, which is critical for running backs Elijah Tau-Tolliver and Jace Larizio to flourish.
• Defensively, Michigan State is undergoing significant personnel changes, especially at linebacker and secondary, but boasts junior safety Nikai Martinez as a leader and top tackler.

Key Trends and Betting Angles

• Michigan State is dominant at home against non-conference opponents, winning eight of the last nine games at Spartan Stadium.
• Western Michigan struggles historically on the road versus Power 5 teams and has failed to cover the spread most times as an underdog recently.
• The Spartans have failed to cover the spread in their last five games, indicating potential value for bettors on the Broncos to keep it closer than expected.
• The combined history suggests a defensive-minded game trend; both teams’ recent non-conference games lean UNDER the projected total.
• Western Michigan tends to fall behind early in games against Big Ten teams, losing the first half in 19 of 20 such games, which could set the tone for the full contest.

Prediction Summary

Michigan State has the talent, home-field advantage, and structural advantages to control this game, though the large point spread may not be fully covered given their recent difficulties against the number. Western Michigan can be expected to make some competitive plays, but their historical struggles on the road and early possession deficits versus Big Ten opponents make an upset unlikely.

Expect the Spartans to lean on their improved offense to put points on the board, while the Broncos will try to keep the score low, resulting in an UNDER game in the mid to high 40s.

Final Prediction

Michigan State wins 31-13, covering the spread narrowly. Take Michigan State -20.5 and the UNDER 49.5.
