I wish I knew what was discussed back in 2005, but if the numbers I found were correct, it's borderline insanity that UNI got an at large bid over WSU.
WSU had a better overall record, finished ahead of UNI in conference, had a better RPI, actually won a game in the MVC tournament (UNI was 1 and out) and could certainly be argued they were the better team, having beaten UNI handily in Cedar Falls while losing at home by one on a buzzer beater (offensive foul) 3.
It would appear that the only important criteria was the record in the final 10 games (which at 4-6 just ignores WSU's 18-3 start) and it also appears that the selection committee was looking to add a 3rd Valley team as otherwise UNI's resume is pretty weak.
My point is that UNI could be in the mix as the 3rd Valley team (assuming WSU finds a way in).
