2. Nick Johnson, Arizona: Forget ACMcDAT negligence: The best argument for keeping the rest of these rankings fresh resides in Tucson, Ariz. Johnson is an efficient scorer and all-around offensive player who also just so happens to be an elite perimeter defender. On Wednesday, the former gave Arizona the decisive go-ahead margin it needed in a 3-point survival at Stanford. But it was the latter -- that defense, and how coach Sean Miller implements Johnson alongside the Wildcats' brutish interior core -- that held the Cardinal to just two field goals in the final 10 minutes. Before Johnson iced his 3, he made one of the best help-defense blocks we've seen all season. It was his national-player-of-the-year case wrapped in one tidy highlight package. In any other season, he'd be No. 1.
