I feel bad for them. Not because it's some risk to Tennessee, but because they were deserving of that spot in the tournament. I've said it countless times: lower conferences should eliminate the conference tournaments. They should opt for a model like the Ivy league, where the regular season conference champion receives the automatic bid. This, however, won't happen because of $$.
Undoubtedly, Norfolk St., MTSU, or [insert any conference champion here] was the best team for their conference all season. I mean Norfolk & MTSU were a combined 38-1 in conference play. They were far and away the best teams in their conference this year. From December to March. But, a team gets hot for 3-4 days and wins the conference tournament and takes their bid away. It sucks. I know the normal response will be "well win your conference tournament," but that can be a challenging thing to do. So, I do think it sucks, and I feel bad for them.
Further, it doesn't represent the conference in the proper light because they won't have their best team in the NCAA. It's not a true representation of the conference's abilities.
Just my .02.
