Punishment: 4-game suspension
The demise of the 2011 Los Angeles Lakers was one of the most cringe-worthy events of the NBA season, and instead of losing with grace they decided to go out like total punks. With his team down by 30 with just over eight minutes to go, Lakers' center Andrew Bynum decided that Mavericks' guard JJ Barea was not going to score anymore, no matter what; when Barea cut up the Lakers' defense again and got to the rim, Bynum delivered a vicious elbow that got him immediately ejected from the game and suspended to start the next season. Ripping his shirt off was a nice touch though.
