Kellen Winslow
Now, first a disclaimer as we all know Winslow is a sick and horrible person, but this was a great on-field display. He battled against extreme dehydration and injuries in the 1981 AFC divisional game. San Diego played the Dolphins on an iconic day that we remember as ‘The Epic in Miami.’ There were a bunch of great displays in this game but Winslow stole the show. That’s because he flung the pain barrier out of the window.

He endured an agonizing pinched nerve and received multiple stitches but kept going. Winslow famously blocked a field goal and had an amazing 13 receptions with one touchdown. In the end, his teammates carried him off the field because he couldn’t walk. Winslow put in the gutsiest performance of his life. (via Chargers.com).
