19. Joe Greene – Pittsburgh Steelers:
Greene is an NFL legend who was the main player on Pittsburgh’s “Steel Curtain” defense of the 1970s. He deserved every bit of his Hall of Fame status.
Yet that doesn’t mean he was a nice guy while obtaining it. Greene was known for a raging temper. His style of play was focused on making his opponents fear him, and they did. For example, he once kicked an opposing player in the junk as they lay on the ground, punched a Denver Bronco, and spit in the direction of famed Minnesota Viking Fran Tarkenton.
In a 1979 game against the Houston Oilers, Greene told Houston QB Dan Pastorini, “If you come into the end zone, I’ll beat the crap out of you! I’m gonna kill you!”
Needless to say, Pastorini didn’t come into the end zone.
