How a team travels - it's fans, not it's big man - and television draw are huge considerations, especially this year. Remember Calhoun's tift with that activist reporter? It's important that these schools make hay when the sun is shinin'.
In a Utopian tournament, sure, the best 65 teams would get in and we'd see the best basketball. But would a number two seed out west be better for Duke and it's fans than say a number three seed in the south? No, and it wouldn't be good for ticket sales or TV revenue. But these are real issues that must be taken into account by the committee that really have nothing to do with basketball.
If being a fan were logical, we'd all be Duke fans but some of us were born to a different blue.
