Re: College Football III: We may lose, but we keep the score close!
It's already being speculated that the Big East will look to both add more football teams and trim the weaker non-football schools. Although PC isn't in the greatest of shape, I think Seton Hall and DePaul should be more worried.
Well, there's two separate things that will be at play here:
1) The ever-present rumors of a split. If the split happens, no problem for the other schools (assumed to be the non-football schools minus Notre Dame; speculation is that Notre Dame will opt to join in the "football Big East" whether or not they actually will put their football team there); they've got the beginnings of a pretty good hoops-centric conference and will probably invite other top-flight Catholic schools to come aboard (Xavier, Dayton, Butler, etc.).
2) If there's no split, I think the Big East will do their best to accommodate the five "charter" Catholic members in the alignment but give them the "I think your interests might be better served playing elsewhere" speech (in other words, they won't be formally booted, but pressured in such a way that is pretty indistinguishable from it). This is especially true if Villanova opts to move to FBS football, which will put the conference balance at 10 football schools (plus football-minded Notre Dame) against the other six.
I think the "dream" (i.e. with minimal disruption to current membership) alignment for the Big East would be a 12/16 football/hoops alignment, with Villanova and Notre Dame joining the football side*, picking up another "football" school (UCF? Houston? Memphis, if it'll keep the hoops schools happy?), and keeping in the basketball/Olympic sport alignment St. John's for NYC/MSG presence, Marquette and Georgetown for hoops quality, and Providence (cause, why not?).
*I did say a dream alignment. This does omit much more pie in the sky dreams like attracting Penn State or Maryland, or bringing Boston College back into the fold, or something drastic like the implosion of the Big 12-2. Considering those possibilities, having Notre Dame commit to the football conference is infinitely more reachable.
