Michigan (8-3) plays at Michigan State (9-2) tonight. Michigan is favored by one—a rare instance of the Spartans playing as home underdogs.
I think it is extremely likely that the winner of this game gets a share of the Big Ten title. This is Michigan's last difficult road game, and their only remaining tests after tonight will be at home against MSU and Indiana. I expect them to win both games, but they definitely won't lose both. So a win by Michigan puts them on course for 14-4, with a real possibility of 15-3. It's hard to see anyone getting ahead of Michigan if they win tonight.
Michigan State still has road games at Michigan and Ohio State, and home games against Indiana and Wisconsin. I expect them to go 2-2 in those four games, so a win tonight gets them on pace for 14-4 as well. 14-4 is very likely to win a share of the title.
So, high drama. Who ya got, Chorlton? I'm taking State.
