Michigan vs. Duke Prediction

For tonight, my prediction for Michigan vs. Duke is a fairly straightforward one.

Duke moneyline (+140): Duke has a strong chance to beat Michigan today because its roster construction and matchup advantages favor a physical, half-court game — especially with Cam Boozer leading the frontcourt. Boozer’s scoring versatility, rebounding, and ability to draw defensive attention give Duke a reliable offensive hub that can exploit mismatches and slow Michigan’s rhythm.

Michigan vs. Duke Odds

• Moneyline: Michigan -165 | Duke +140
• Spread: Michigan -2.5 (-105) | Duke +2.5 (-115)
• Total: Over 148.5 (-105) | Under 148.5 (-115)
