UNC as a 4 seed is about right. They have come on and are playing pretty well right now. They have quality talent (in fact, if K were coaching that talent I think they'd be a 2 seed - they'd be much tougher).
But, Oklahoma as a 3 over Maryland? With 10 losses? That's absurd. The committee is really overrating the Big 12, imo. KU should not be a 2, imo, with 8 losses. Including a slaughtering by UK and a crushing loss to Temple (77-52).
And, if the committee bases the seedings on more than just the stats over the season, but also factor's in the "eye test" and also the quality of play currently - Louisville simply is not a 4 seed (not with the loss of Smith). And, I'm not a hater on them, but this L'Ville team, "as is," is a 5 or 6 seed, imo.
