EJ was a warrior that year battling his knee injury. He was so athletic. He could easily do 360, between the leg dunks when he got here. Unfortunately, he just couldn't get over injury and find that explosiveness. Don't forget the 2012 Title Run was in large part due to his clutch shooting.
The only real disappointment that I have with EJ was his intentional shot on McGary early in the game. The Hawks knew Mitch set hard screens and EJ wanted to set a tone early. That kind of crap is unacceptable in my view, although, I know this kind of stuff happens all of the time.
