Fez, McDyess was a really different case... According to Wikipedia: "Early in the 2001–2002 season McDyess suffered a serious knee injury, a Patellar tendon rupture, that required season-ending surgery. McDyess struggled to play through the injury, re-aggravating it several times and going through additional surgeries over the next few seasons. He was sidelined due to injury for the remainder of the 2001–2002 season as well as the entire 2002–2003 NBA season. McDyess was traded to the Knicks on June 26, 2002[1] in exchange for Marcus Camby, Mark Jackson and the draft rights to Nenê, the seventh overall pick in the 2002 NBA Draft. McDyess began the 2002–2003 season as a highly anticipated addition to the New York Knicks. But on October 8, 2002, with 1 minute 55 seconds left in an exhibition game against Phoenix, McDyess reinjured the knee while dunking a rebound.[2] He would undergo another surgery four days later. In the 2003-2004 season, McDyess was traded to the Phoenix Suns after just 18 games with the Knicks in an eight-player deal that brought Stephon Marbury to New York.[3] He remained healthy while in Phoenix for the remainder of the 2003–2004 season and became an unrestricted free agent in the summer of 2004. In the 2004 offseason, his knee was declared healthy and the Detroit Pistons signed him for the full mid-level exception."
I think I just described most of the internet.
