38. Antonio Brown
Perhaps the humiliation of losing to the Jets was too much for Brown. The Buccaneers trailed 24-10 in the third quarter when he tore off his jersey and walked off the field. He didn’t just threaten to leave his teammates in the lurch but followed through.

This infuriated coach Bruce Arians, who said that Brown would never play for the franchise again. This was a major humiliation because Brown was already a controversial figure. He rehabilitated his image in Tampa before ruining it again (via Sportsnet).
