They took Michigan into overtime, Wisconsin hasn't really proven itself yet imo and I think they may be caught by surprise, it'll be a close game regardless, though. (Wisconsin is favored by 10.5 in the odds right now which I think is probably their ceiling)
Spread has actually moved towards Wisconsin, opened at 9.5.
Both teams have a lot of injuries. Wisconsin had 5 starters on the injury report, while 11 Indiana starters have been injured at various times this year.
I'm worried about the game, but I would be less so if their all-World Freshman RB Johnathan Taylor is able to go and Safety D'Cota Dixon is back.
