The big problem for the #1 seeds right now, is that the two conferences that have the best chances at getting many top 50 wins (Big 12 and Big Ten) may not get any #1 seeds.
Teams like Texas and Oklahoma are playing havoc in the B12 but didn't really have a good OOC. In the Big Ten you have Michigan bouncing back from a poor start, and some of its early season stars sliding in Michigan St and Wisconsin.
It opens the door for two teams that are a bit of a "mystery" in Wichita St and San Diego St to get #1 seeds. The MWC like the MVC is down this year.
I'm not sure if Wichita St is a top 5 team if they go undefeated. But if they go undefeated, I just can't see the committee not giving a #1 seed to them. To me its not even much of a debate -- even if the committee questions how good they are, at 33-0 or whatever, they get a #1.
I think where debate will get interesting going up to Sunday is if they lose 1 game. Then they may get assessed a little more fairly, and will not be forced to the top line.
