Whether we go to the Insight, Little Caesar's Pizza Bowl or an at-large big depends on two things:
1) If Michigan becomes bowl eligible (with a win over Ohio State). We'll know the answer to that on Saturday.
2) Whether the Big Ten has one or two teams in a BCS game. Right now, we're likely to have 2 teams, but if we beat Iowa and Michigan State beats Penn State, it is possible that only Ohio State goes. Even if that's the case, we still won't know for sure until the BCS selection on December 6.
So, I really can't foresee the announcement on a bowl destination until December 6.
