Baylor is getting lots of love because they now have 3 wins over top-10 teams: Oregon, Louisville, and Creighton (plus another one over then-#24 Michigan State). It's pretty tough to argue against that resume (and indeed, Baylor even got 6 first place votes).
UCLA vaults thanks to a high-profile win over big, bad Kentucky (at Rupp, no less). Hard to argue against that win too; it's worlds better than anything on our resume.
I don't care about December polls. I'm more than confident that the conference season will sort things out, the cream will rise to the top, and we'll be right in the mix at season's end. Plus, we're still ranked ahead of the cheats.
