To me, the only way to measure success is to win games in the NCAA tourny. Conf Tourny wins are nice, but to me they don't mean squat.
Both coaches, Pastner and Counzo, are young coaches with a lot to learn. Both are going to achieve a high degree of success in the years to come.
As far as who is better right now, that is debatable on both sides. Counzo has more big wins, but he also has some very bad losses, and his recruiting is kinda suspect. Pastner has made the tourny multiple years and he has been pretty good with recruiting, but has only one win in the NCAA.
I think next year, the heat will be on both coaches. Pastner has a stellar recruiting class to go along with some solid upperclassmen, but if he doesn't improve on his last year (make it to the sweet 16), he will be under a lot of pressure from Tiger fans. I don't think his job will be in jeopardy though. Counzo, has his best team to date at UT, so he will be expected to make the NCAA tourny. If he barely misses the tourny, I think he will be able to make another year. If by the end of the year he has no shot at making the NCAA, then he will more than likely be gone.
