That's what the Mountain West thought when they added TCU. Google "the mtn" and tell me how that's gone.
TEXAS is the school in the Dallas market, even if they're not in the Dallas market. Kind of silly how that works, no?
No question that UT is the number one school in the Dallas market. That's the nature of the state flagships. Unfortunately for the BE, there aren't many of those around that are not already in a BCS conference. (I believe Utah is the largest state without a BCS conf member). Louisville, Cincy, USF and Pitt all live in the shadow of state flagships. Hopefully, though, some folks in Florida and Ohio are watching Big East games who never cared before.
The Big East strategy from the beginning in the 70's has been to pick members in large TV markets. These schools are frequently overshadowed by pro teams, but have a niche. TCU would give the BE a niche in Dallas.
Unlike the MWC, the BE is not looking to form its own regional sports network. Rather, it seeks to have its games carried on ESPN and through ESPN Regional on local stations and existing RSN's. This is a much lower barrier to clear than the Mountain.
Anyway, still looking for alternative suggestions with good arguments.
