Brian Jones just brought up an interesting scenario on The Ticket.
#24 ranked Michigan has Wisconsin and Ohio State left. They win those two games, then beat Wisconsin again in CCG, does 11-2 Big 10 champ Michigan get in?
EDIT looks like Michigan is 19. Not 24 like Jones stated.
I would say possibly but very unlikely. They'd have two losses and probably no wins over Top 10 teams, it seems like that would be a tough hurdle to get over. Going to #24 to #4 in three weeks seems pretty impossible. They can probably only get to #10 or so in the next couple weeks, then a win over Wisconsin in the CCG, I don't see how that could move them all the way to #4. Not enough teams in front of them will lose.
