Pat Riley and Miami Heat
In March 2008, a month after being traded from Miami to Phoenix, Shaq insulted former Heat teammates Ricky Davis and Chris Quinn -- "We have professionals who know what to do. ... I'm actually on a team again," he said of the Suns -- and ripped the Heat's training staff. Riley called Shaq's criticism "sad" and defended Miami's medical staff: "He can do whatever he wants to do to me. That's OK, I don't care. But those men, they tried. ... That upsets me more than anything."
