Harden is pushing the Player's Association to allow Houston to play with 2 basketballs next year.
After this trade, I have Houston out in the first round next year.... Unless Westbrook really develops into a set shooter. It's difficult to really tell what kind of player Westbrook is outside of being a very traditional 90's SG Slasher. I think he is a fairly decent dump off passer, but as his career progresses and he is less of a shooting threat his assists will suffer. He isn't a rebounder or much of a post/defense threat. Playing with Harden, which I'm going to assume isn't going to do anything to lower his USG, Westbrooks stats will definitely fall. I don't know how well Harden will do with Westbrooks 30 shots a game when Harden takes the same amount. Harden had issues with Paul's touches even though Paul was pretty efficient and makes his touches count.
I hope I'm pleasantly surprised by Houston next year, maybe Westbrook will humble pie.
