I think I've watched every youtube video of Perry Jones available. I agree his tools are crazy, and I agree playing behind Durant and Co. may have slowed his development, but something else is up, it could be in the mental aspect of competing, or the exchanges between players, or something that has to do with the way he views himself that stops him from reaching past being a basic roll player.
I'm not a phycologist, but I know he's had a tough up-bringing to deal with, and we all know some players just do not play with a consistent motor, like Jeff Green as example. (Great guy, nice career, no consistent motor)
At his age, I'm hoping Coach Stevens and Danny can find the key that unleashes him, and to get him to play near his potential. Because his potential is pretty high.
