I hate the weak ACC matchup game, but Purdue gets Maryland, UW and UM home and away. Plenty of chances for signature road wins. All of the single plays on the road and home are winnable. I see 12-13 wins as reasonable with 15 as an upside.
Purdue
Home: Michigan State, Northwestern, Ohio State, Penn State
Away: Illinois, Indiana, Minnesota, Rutgers
Home/Away: Iowa, Maryland, Michigan, Nebraska, Wisconsin
