To answer the question as to when RU will leave the BE it won't be until either the ACC or Big 10 comes calling at which point they'll be replaced by another fb school and won't we all be looking forward to the big SJ - Southern Mississippi or SJ-East Carolina bb rivalry that will ensue.
BE has come up with some 42.5 milllion as a result of WV (20 mil), Syracuse, PITT and TCU (5 mil each), Houston, SMU, Cntl Florida, Boise St, San Diego St and Temple (2.5 mil each) either leaving or joining the conf so if they're willing to give up to 3 mil to Villanova to assist them in decideing whether to upgrade (a truly dumb move, IMO) I think it reasonable to assist Rutgers for money lost as the result of giving up a home game. Playing a home and away series with another member wouldn't be fair unless every conf school played a home and away series but would also be a scheduling nightmare as the other schools would all have to drop an out of conference opponent. Then all of those schools that had to give up a home game would be justified in asking the BE for a reasonalbe dollar amount for money lost with one less home game.
