The New York Knicks thought they had landed a superstar when Julius Randle broke out a couple of seasons ago. He was dominant in the paint, put the ball on the floor, and played the best ball of his career in the regular season.
Then, just like something out of Space Jam, the Atlanta Hawks took his superpowers away by double-teaming him and getting into his head. He hasn't been the same player ever since and will likely never be.
