20. Rudy Tomjanovich
Ever had someone threaten to "smash your face in?" Well, that's what Kermit Washington did to Rudy Tomjanovich. Literally. During the '70s, fights were a regular occurrence in the NBA and ABA (you've seen Semi-Pro). Kermit was in the middle of a scuffle when Rudy tried to calm things, but instead received a knuckle sandwich. The hit, which caused a broken jaw and multiple facial fractures would eventually lead to Rudy T's early retirement.
