My predicted lines:
Ohio State -17, O/U 57
Purdue -14, O/U 54
Kansas -26, O/U 42
Army -4, O/U 44
Bets and why:
Kansas/Duke Under 51.5 -110
Duke's offense can't run and Kansas's defense looks incredible so far this season. I don't see Duke getting to double digit points unless they backdoor me in garbage time. Kansas has been scoring nicely but they've been using the running game to do it which grinds the clock. The Blue Devils have not stopped the run so I expect the Jayhawks just to grind the clock and help out the under with the running game.
Ball State Cardinals +8 -110
I feel like a moron playing this team but they should be able to stay within this number. The fact that Army runs 95% of the time helps underdogs cover because it shortens the game. Ball State has played horrible but they are not as bad as they've shown and I think they'll be able to run on Army. Army's D is simply not as good as they have shown and Ball State is much better then they've played.
