fossil, the intent of this post was not to hypothesize on limits of geographical isolation and more on what may become the inevitable for Big East football.
The purpose again of my post was not a decision that Syracuse and UConn may want, however, may become a decision they have to eventually make.
fossil if you can tell me why the Big East thinks staying together in the current format at the risk of raids and losing more football schools is worth it, then you have answered the million dollar question.
I did realize that-my apologies. Even if the distances Syracuse and UConn became too problematic, I doubt they would de-emphasize football. Instead I suspect they may opt for independent status. (I should have been clearer that their status was my main point.) If they could play each other, Army, Navy, ND, and a Northeast 1AA, that would be a good start to a regular schedule.
I guess I diverged from your intent because I (unfortunately) don't see geography as much of a problem in the eyes of Football Bowl Subdivision schools.
As for your question for me...I don't know why the Big East keeps its current form. (Aside from the basketball history.) I agree that an all sports conference would be best for football. And I think for basketball and other sports as well.
