Ray Nitschke
Ray Nitschke played as a linebacker for the Green Bay Packers from 1958 until 1972. He truly came to his own under coach Vince Lombardi, but he was always known for his meanness and hyper-aggressiveness. He said: “I’ve always learned that the best way to play the game is to hit your opponent a little harder than he hits you. It’s self-preservation.”
Steve Atwater
Steve Atwater played as a safety from 1989 until 1999 for the Denver Broncos and New York Jets. Atwater certainly helped the Denver Broncos to consecutive Super Bowl wins, especially Super Bowl XXXII, where he made half a dozen tackles, broke up two passes, and forced a fumble on a sack.
