Villanova had their shot. They were given the same opportunity that UConn, St. Johns and Georgetown were: upgrade and you're in. Everyone turned it down except UConn. The ship has sailed.
A - Villinova and the other private schools were given the same invitation
as UConn, but obviously they did not have the same level of support, ability or faith to take advantage of that invite. I agree, they perhaps could have/ should have given the idea more insight, however.
B- Times have changed for the BE. The concept of the BE considering additional options suggests that standing still may not be in their best long-term interest. BCS or no BCS, the conference has the business-like responsibility to care for itself and in that respect there may be the need to do something more for football. This is merely one option worth reconsidering, IMO.
C- Is it safe to say the BE would accept Villanova football if they chose to upgrade now of their own volition? IMO, gleefully so.
As I've said before the BE may turn out to be perfectly fine as is for the next 100 years. This is just one man's speculation on a possible solution to a possible problem. S'all.
