Assuming a split in 2010, is there anything the football schools can do to make continued Big East membership more attractive to Rutgers than a potential Big Ten invitation? This is the time for them to be proactive & fend off another defection. It would not be wise for them to wait to react to such a move as they did with Miami, etc.
In many ways, Rutgers is the most valuable franchise in the Big East. Its state population & university size are unmatched in the conference. As a flagship, it has the identity to attract both alums & adopted fans. Its location in the NYC suburbs is critical for a Big East Football. Only UConn & WVU are flagships in the conference, but both are in small states. Among the rest, only Syracuse plays without other major collegiate competition in its backyard.
I honestly don't think there is anything the BE can do - realistically - that can keep ANY team from leaving and that includes the pipedream 14 team SEC or ACC. The reason is that the Big10, ACC, and SEC offer more exposure, money, and academic advantages (with the Big10 and ACC anyway) that the BE doesn't have and will probalby never have compared to those other conferences.
The only scenerio I can see to prevent anyone from leaving is the formation of a NE based all sports conference with AT LEAST PSU at the core of the conference. I know - not happening.
I have read that some proponents want the BE to expand to 9 or 10 in case of another raid. Why? Do you think adding an ECU, UCF, or Memphis will suddently stop a team from leaving? I don't.
The one caveat I have for Rutgers is that they can be a big fish in a small pond in the BE. If they move to the Big10 they will be a small fish in a big pond. Their athletic budget is dwarfed by the budgets of Michigan, OSU, and PSU. Just something else to think about.
All the things you mention Friar would make any team think twice about staying in the BE if invited to the Big10. The NE is one of only two regions where the number of college FB fans can increase (the other is the Mountain West). PSU and ND have the lion's share of these fans in the NE. Another challenger to those two is good for college FB and the NE in general.
