Nothing surprising here.
Amare has the worst basketball IQ of anyone with his supposed resume' that I've ever seen. He doesn't understand how to co-exist with other bigs around the basket. In PHX he was an athletic dynamo, allowed to run free as part of a fast, undersized team. He's no longer that athlete and he seemingly hasn't learned any other aspect of the game since leaving the Suns.
Remember that nobody on the Suns... not players or managenment... lamented that he left.
