I have read that there is a chance there may not enough bowl eligible teams to fill all the bowls this year.
In that case they start looking at 5-7 teams with the highest APR, and I hear Illinois is 2nd on the APR list. So it might be possible for Illinois to finish 5-7 and sneak in an invitation to the Quick Line Bowl in Detroit.
Also it looks like the winner of the Rutgers/MD game will be bowl eligible, so the Big Ten is certain to get at least 1 more bowl team.
