You could see Tulane elevating things the last couple of years. Sehic was a monster at times last year, see the game where Tulane trounced SMU in NOLA. He gave us fits at times too. Tulane's issue is whether or not they get good enough or even consistent guard play. They've been turnover prone the last few years.
ECU- I think Dooley will at least get them to a competitive level in the AAC. Remember this conference has 8 really good teams with a history of tradition in men's basketball, UCF who is relatively new but has been building their program over the last 8-10 years, and then Tulane, ECU, and USF. Dunleavy was a good choice for Tulane, and Dooley is apparently on the fast-track to making ECU respectable. The Orlando Antigua experiment at USF was a disaster so my guess is they're going to struggle a while longer.
SMU- It's not too long before they are consistently picked to finish 7th or worse in the AAC until they get rid of Jankovich.
