PJ Tucker is the best choice ever.
DeAndre Jordan has no business in third place, and LeBron has no business there either. DeAndre Jordan is the same thing than Ibaka on previous years (ironically, Ibaka finally was really a great defender this year, and did worse in the voting, and LeBron is kinda like Kobe on 2012, but maybe even worse. LeBron not only wasn't elite on defense, he was just bad... but there he is, and he'll probably even be an All-Defensive First Team.
Glad for Noah, who I do think did a great job. Also glad for Hibbert, who even with all the hate he's getting (it is true he is VERY bad on offense and a bad rebounder), he's still an impressive defensive player. No one's better than him in the paint.
