Bennett won a national championship. Can't take that away, but he also had a few horribly embarrassing losses and his teams were awful to watch.
The first 1 seed ever to lose to a 16 seed (and while ranked number 1). Since the Championship, they lost twice as a 4 vs. 13 in the first round. Then last year's 34 point blowout at VT and the 42 points they scored in the NCAA Tournament First Four blowout.
Bennett seems like an OK guy, so I hope he lives a happy life, but his teams were boring to watch and his tournament results were terrible on the whole (and especially of late). Now he whines about the state of the game and leaves his team 3 weeks before opening tip. Maybe this is harsh, but I really don't think UVa or NCAA basketball will miss him (other than the love for an early round upset).
