I think 2K has done a great job of providing roster updates along the way, ensuring that most players in the game play like their real life counterparts. Sure there are little art modifications here and there that need to be done, but the big picture of the post-release support is pretty good. It's as good as I ever remember it being in the 2K series, and I've been playing since 2K3.
On topic - JR Smith in the game, and he brings some JR Smith cheese along with his arrival. This guy can light it up in this game. He has the perfect blend of Swiss and Cheddar, the Swiss being he can get to the rim and finish with a nasty dunk, the Cheddar being he can spot up and hit the 3. It's a perfect blend of 2 fine cheeses.
