I think he deserves it. The only real negative I have for the dude this year is that his three ball has kind of abandoned him, especially given how many of them he shoots. But he's a transition nightmare, his midrange game is one of the best in the league, he plays both ends, and he has arguably been more consistent over the course of the season than even JT.
Individual success is there. Team success is there. Give it to the guy so we can pay him and keep his ass in Boston, lol.
Sidenote: I still feel like he doesn't get respect from the refs, given his style of play. He's a physical offensive player and he puts a lot of pressure on the rim. Yet he really doesn't get many FTs despite that. Not sure why that is.
