Evan Turner, Ohio State. Or Willie Warren. Though I bet Robbie Hummel, Luke Harangody, John Wall (and everyone else on Kentucky), and Cole Aldrich/ Sherron Collins will get a lot more attention.
And if Kemba Walker gets his outside shot to fall... he might be one of the best players next season.
(That's to answer "best player" next season. I think preseason player of the year will go to Harangody and at the end of the year he'll have a hard time keeping those votes. Willie Warren, or maybe even a player lie Damion James might sniff the preseason award.)
