Laron Profit had a limited, not overly productive four-year stint in the NBA, with two of those seasons coming as a backup on Michael Jordan's Washington Wizards when MJ was the president of basketball operations prior to his un-retirement. On Matt Barnes and Stephen Jackson's "All The Smoke", Detroit Pistons legend Richard Hamilton claimed that when Jordan worked out with the team one afternoon, not an uncommon occurrence in those years, Profit once made fun of Jordan, claiming he "can't guard him with those old-ass knees." Jordan responded by trading Profit to the Orlando Magic at the end of the season.
The Magic later released Profit, who played in Italy and China before returning to the NBA in a limited role in 2004.
Before you start assuming this was just Jordan finding a way to dump an underperforming player, Hamilton confirmed that MJ held a grudge in a exit meeting with him.
Oddly enough, Jordan later traded Hamilton to Detroit in exchange for Jerry Stackhouse. When he was in charge of the Charlotte Bobcats, he traded Jackson to Milwaukee. Many an NBA player had felt the wrath of Jordan and ended up on another team.
As great as Jordan is, he's a notoriously grouchy guy and someone who will hold a grudge until the day he dies. Profit clearly touched a nerve, and his pro career never recovered after Jordan traded him.
