Brian Scalabrine was a bottom of the barrel NBA player. He was good enough to stay in the league for years but he'd only play about 13 minutes a game and averaged 3 points a game. Basically he was the guy who would play a few minutes and not completely tank the game while your actually good players were getting a rest.

After he retired he went around playing amateurs and completely dominating them. He became semi famous for his saying "I'm closer to LeBron James than you are you to me."

He is still doing it, last one that got popular was a month ago https://www.boston.com/sports/morning-sports-update/2025/03/...
