Just going by Lunardi's latest for simplicity, not trying to argue how good he is or isn't.
I think the top 6 are pretty well set and will be some combination of these 6 teams
1's: Auburn, Duke, Alabama, Houston
2's: UT, Florida
Beyond them:
Michigan State: @Maryyland tonight, vs Wisconsin Sunday, @ Iowa March 6th, Michigan March 9th.
Texas A&M: Vanderbilt tonight, @Florida Saturday, Auburn March 4th, @LSU March 8th
Iowa State: (I actually think the loss to OK State hurts worse than them just falling to #9 overall, and we may leap them with a win tonight, certainly if we beat Auburn). Remaining games: Vs #17 Arizona, vs #25 BYU, @Kansas State (who is desparate).
Wisconsin: @Michigan State, @Minnesota, vs Penn State. Iowa probably winds up as a 2 seed, especially if they win @ Michigan State
Probably best case scenario: Michigan State loses tonight, Wisconsin loses Sunday.
Texas A&M loses hopefully 2/4 with Florida and Auburn on the schedule.
Iowa State could lose multiple.
We obviously have to take care of our own business. Win @Oklahoma and beat LSU. Win 1 of Auburn or @Mizzou--3 seed is safe. Win all 4, jump to a 2 seed.
For practical purposes, I'm not sure it matters a ton. Whoever you knock out of the 2 seed probably is the 3 seed we end up playing in the Sweet 16. I think the goal/hope is be a 2 or 3 to avoid the 1 seeds as long as we can (maybe even hope for an upset).
