Lieberman profiles the four #1 seeds:

Duke: probably would have won last year if Mo was on the court -- this year, they don't really have a weakness.

Tennessee: they've recovered nicely from the Moore injury, and they're still improving going into the dance.

Penn State: yes, they do have other good players on the squad, and they had a very tough nonconference schedule, which should help prepare them for the tough East bracket.

Texas: deep and balanced, but sometimes lacking in team chemistry -- seeing their losses to Tech and OU might give opponents confidence.

Nancy doesn't really make any picks here (so far, none of the ESPN columnists have --why?), but it looks like she thinks Duke has the best shot to win it all.
