Lots of good talk and discussion in this thread. I'll go with :
Midwest
1 - Kentucky (overall #1 seed)
2 - Kansas (last on the #2 seed line, also I think the NCAAT SC has good reason to put them in UK's region. 1) KU has already lost to UK, so it gives them a storyline for KU revenge, a chance to do better this time around and make it interesting ... plus 2) if KU loses which would be expected, it's no skin off any other teams' nose because everyone will be happy that KU has to lose to UK again so that better matchups vs. could happen in the Final Four and title game, 3)KU should - at the very best for them - last on the 2 seed line, 4) Midwest is KU's natural region)
West
1 - Wisconsin (last#1 seed) plus, as I understand it, the west region winner faces the midwest, so they don't want to stack the other side of the bracket with too many of the top teams that actually look like they could have a chance to beat UK only having to knock each other off en-route to a shot at UK.
2 - Arizona
South
1 - Virginia - (third #1 seed) Even though they lost, they still won the ACC regular season, which, in my opinion, should net them the third #1 seed over Duke. Although it is really close to a toss up that they could simply switch Duke to the #1 seed in this region, swapping with UVA and making UVA the 2 seed in the east with Nova'....
2 - Gonzaga
East
1 - Villanova (second #1 seed) - will look good to give them to Duke as a second overall #1 seed, a team Duke could handle
2 - Duke : slides to this slot as a result of the loss. Still a good shot at winning a weak region, plus it also sets up what I think the NCAAT SC will want to do for storyline reasons : put Maryland as the #3 seed in the East to create that rivalry matchup with the blue devils that ended when the terps' left the ACC....
That's the bottom line for me. I think it really just comes down to who they justify between Duke and UVA getting that third #1 seed, also all of this is assuming Wisconsin and Nova win out to secure their #1 seeds. Should one of them fall, it opens the door for Duke, most likely, to nab a #1 seed. Gonna be really interesting to see how the NCAAT SC justifies whatever they do ....
