I think its a combination, partly he is really awkward and gets away with going over the back and tipping the ball around a lot. He gets the benefirof being on LeBron's team and they dont call a lot of fouls that should be. I hate players like him that play like crap/ dont play and then against certain teams play great. It isnt just matchups it is lack of motivation most of the season . You can tell watching him, the way he looks like he is running uphill into a hurricane he doesnt play hard most of the time
