While I agree SAS says things to rile up controversy and get views this wasn't one of them. Yes he was wrong, Sully has played fairly well in the NBA, but what he said doesn't make him outrageous. He said Sully knew the game but didn't have the athleticism to make it in the NBA, completely understandable. It's an opinion.
As for Fab Melo, I don't think anyone knew how incompetent he was at basketball, playing in a zone in college really hid his deficiencies.
