The 1 line: Villanova, Virginia, Xavier, Kansas
The first 3 are easy. But man I don't know. Can you leap Michigan St all the way up there? I almost left Purdue on the 1 line. Clemson, TTU, and Cincy (and Auburn) all have thin enough resumes. In the end, Kansas has: the #1 SoS, 9 Group 1 wins, and an average RPI win of 80. These are magic bullets.
The 2 line: Michigan St, Purdue, Clemson, Texas Tech
MSU has concerning metrics which caused them to drop, but winning cures all ailes. And now with a signature win in tow, here they are. I wouldn't argue against almost any order of these four teams. The SoS numbers aren't great for MSU and Tech so I wouldn't be surprised if they wind up on the 3 line.
The 3 line: Cincinnati, Auburn, Duke, Ohio St
I think these teams are pretty self explanatory. I wouldn't be surprised if the committee cites SoS numbers and puts Duke on the 2 line.
The 4 line: North Carolina, Arizona, Rhode Island, Tennessee
All of a sudden, we're running out of quality teams for the back end of this list. WVU and Oklahoma are punting...Gonzaga and St Mary's aren't quite good enough. Creighton has SoS issues and Seton Hall is losing games now. I just don't know who else you can put here except for these teams.

As you can see, a balancing issue persists. There's no real way to solve it. The problem? The ACC has 4 teams in the top 4, meaning someone has to go west. But Arizona is the only western team, which means North Carolina (sharing the same line as Arizona) can't go west. Therefore it's Duke who has to go, and having a weak 3 seed go in with a weak 1 and 2 seed makes for a soft region. The other solution is to send Clemson to the west, which really isn't fair to them.
Don't be surprised if the selection committee in March artifically fudges the seeds of a couple ACC teams, to make the regions seem more balanced than they are. I also wouldn't be surprised if they automatically put #4 and #5 overall in the west, especially if there's a lot of debate over who should be a 1 seed.
