Rec, here's how I see it heading into today.
Syracuse is the clear #1. Best team, maybe, maybe not, but they have earned the spot just based on UK and KU losing and them working their way up.
Purdue is #2 if they win. They only have three losses, but might be the hottest team in the country after their mid-season 3-game losing streak. If they lose, I think they take a hit, especially as the voters will see a loss without Hummel at home.
I think Kansas will remain #3 and Kentucky will remain #4. Both lost, but both have good resumes and their losses weren't necessarily to crappy teams. You have to figure Tennessee will sneak back into the top 15 and Oklahoma State, while not ranked, will certainly still gain some ground.
Duke might jump to #3 with a win, but I still don't see it. Wins over Tulsa and UVA aren't going to vault them higher than 5 (unless Purdue loses), and I don't think they should. In fact, I wouldn't be surprised if K-State were to jump Duke, especially in the AP poll as they are quietly winners of 7 straight (as impressive as Duke) and had a big week knocking off Texas Tech in Lubbock and beating Missouri.
Purdue Wins:
1. Syracuse
2. Purdue
3. Kansas
4. Kentucky
5. Kansas State
6. Duke
7. Ohio State
8. New Mexico
Purdue Loses:
1. Syracuse
2. Kansas
3. Kentucky
4. Kansas State
5. Duke
6. Ohio State
7. New Mexico
8. Purdue
Then again, polls are just a nice little number by the team name

As I've said multiple times in this thread, 95% of teams are going to lose at least 1 more game in the next 14 days. The polls could all but be scrapped after this upcoming week since the number beside a team's name is no longer relevant, even for media hype or advertisement. It's March Madness time!
