My final `expert guess.' I am going to assume that Ohio State, North Carolina, Florida, and Kansas win on Sunday. If any of them are upset, then I think UCLA remains a #1 seed based on their RPI and the strength of their regular season. Otherwise, the Bruins are the top #2 seed. The Big 10 loser and Georgetown could also make claims to being on the top line.
My top four seeds:
No. 1: Ohio State, North Carolina, Florida, Kansas
No. 2: UCLA, Wisconsin, Georgetown, Memphis
No. 3: Pittsburgh, Texas A&M, Washington State, Southern Illinois
No. 4: Texas, UNLV, Oregon, Maryland
Close: Nevada, Louisville, BYU, Notre Dame
