Iowa. Pretty much knocks Wisconsin outta the West race and makes the Iowa-MN game the West championship assuming other games go as expected (obviously not likely to happen in CFB). None of it changes the fact Minnesota controls their own destiny though.
PS: Gophers are going to win at Iowa 20-17 in 3 weeks. Place your bets early
But I think Iowa winning is better for us overall only because it essentially removes Wisconsin from the equation whereas a Wisconsin win leaves both those teams still in the mix.
In the end, tough to say which result would help us the most because there are still a lot of games left to be played. The good thing is, one of those teams is leaving that game with an L in their record.
I voted for Wisconsin because I think Iowa is better. I'd rather be up on Iowa and have to take my chances with Wisconsin down the stretch than have Wisconsin eliminated but still have to deal with Iowa.
