The Sweet Sixteen.
Only seed below a 6 seed is NC State. This is a super chalk bracket overall. Clemson is the only other seed below a five seed (a toss up with a four usually in the round of 32), and they are a 6 seed. 10 of the top 12 seeds made it through (B12 Baylor and SEC UK missed out). Then two 4s, two fives, a six and an 11. The two fours that didn't make it were B12 KU and SEC Auburn. I see a theme.
Below are the regular season records between these 16 teams. I am pretty sure I got them all.

Houston and ISU stand out for not playing any other Sweet Sixteen team OOC and only playing each other in conference of teams remaining. Perhaps the B12 was a tad overrated this year when their best two teams didn't play anyone OOC. Considering how chalk this went I think this is important to an extent.
In the SEC, Tennessee did decently and at least Bama tried to play good teams though they couldn't win.
SDSU only played the Zags.
Clemson didn't play anyone OOC either and were fairly bad against the other ACC teams.
Purdue is an impressive 7-0 against 6 Sweet Sixteen teams. UNC is 6-3 against 5 Sweet Sixteen teams. Tennessee is 4-2 against 5 teams. NC State as an 11 seed is a surprising 3-4 which is the fifth most wins against the remaining teams, tied with Creighton (3-2).
Ohh and UConn is 6-1 against 4 teams.
