It was really obvious that Virginia didn't deserve their bid. They were by far the worst at-large bid using Torvik's "Performance against Top 100 teams" filter. Something dreadful like #125.
I know they finished 3rd in the ACC, but with unbalanced conference schedules, that doesn't mean as much as it should.
It would be nice if the NCAA would do something smart like guarantee a bid to the top 3 finishers in each of the 6 (5?) major conferences. Then the regular season conference games take on a little more significance. It also establishes some certainty.
Let the conference decide what to do if their tournament winner is not one of the top 3. Presumably take the automatic bid for the third place team and give it to the conference tournament champ.
They'd still have plenty of flexibility with the at-large bids.
