50. Jack Tatum
The vast majority of Tatum's hits were considered legal back in the day, but they didn't call him "The Assassin" for fun. The defensive back struck fear in wide receivers and tight ends who dared to come across the middle while he was playing. His most infamous hit paralyzed Darryl Stingley during a 1978 preseason game. That's right, the hit occured during a preseason game. Tatum never apologized.
