Right now:
Purdue: 1566 (54)
Houston: 1486 (7)
Kansas: 1481 (2)
UConn: 1335 (0)
No on has UConn above 4 on their ballots. That will change, but it means we're not necessarily going to pick up a bunch of easy #1s on individual ballots.
3 voters have us #7, and UNC and Kentucky haven't lost, so you figure we're staying behind those two teams on those three ballots.
7 voters have us #6. In 6 of them, it's either Kentucky or UNC, so, again, we'll likely stay behind them. In one, it's both (they had Tennessee far lower).
Of the many voters that have us #5, most have Tennessee ahead of us. 4 have Kentucky ahead of us, 1 has Arizona, neither of whom have lost.
So I'd say of the 63 possible first place votes, we know for a fact that we aren't getting 15. For at least 4 ballots, we're highest #3. The odds that they'd jump their #7 team over a #1 team who lost is pretty low. Also, 4 -> 1 is a fairly large jump, especially since we didn't dominate that Xavier game.
My guess is some people will keep Purdue. Some analytic forward people will keep Houston. We'll move up across the board and have a range of votes ranging from 1-4 in voters. We may end up with the most #1 votes but end up #2 or even #3.
I'm beting UConn, Purdue, Houston, Kentucky, and UNC all get #1 votes.
