Jim Brown
Jim Brown played as a fullback for the Cleveland Browns from 1957 until 1965. Longtime New York Giants rival Sam Huff said: “Jim was smart. He’d psyche you. I would hit him and hit him, and he’d get up, pat me on the back and say, ‘That was a nice tackle, big Sam.'” Brown was known for being an indestructible force in the league.
