I think it would be in the B1G's best interest for it to advance some $$ to Rutgers, with the proviso that it will all even out in the end. It's pretty clear that RU needs more money right away and the overall athletic program might experience some serious problems if it doesn't get it.
As for the exit fee Rutgers had to pay, I found that entire scenario unbelievable. The AAC did not exist when RU announced it was leaving the BE for the B1G. One could make the case that RU did not leave the BE - the BE left Rutgers, including the CYO's who got off scott free leaving AND taking the conference name with it. One wonders if RU might have done better to play the 2013 season as an independent, though arranging a complete schedule would have been difficult to do at the 11th hour.
