Duke and Auburn are for all intent and purposes locked in like you say.
You are also correct Houston is probably the only team that knocks SEC from 3 #1 seeds.
Only thing we can necessarily control is helping knock Bama off the one seed line.
We do that, and our #1 seed hopes go up a lot.
We are just below them in percentages to get that one seed right now.
I can't remember them exaclty but Bama had like 36% chance, we had like 30 % chance, and Flordia with like 26% chance. I think Kentucky even had an 8% chance at a #1 seed.
We all know that isn't happening, tho lol.
