Junior Seau
The late, great Junior Seau was as relentless and tough as they come.
He was a 12-time Pro Bowler, a six-time All-Pro and a posthumous Hall of Famer. He made two losing appearances in the Super Bowl, one with the Chargers and the other with the Patriots. His pain, and subsequent early death, has been well-documented and it’s terrible to realize he was suffering so much, but, damn, was this guy good.
