What a player he was I watched as a college player a real animal. He was hated after his knee injury. Some players gave him the respect of not trying to cut his legs from under him.
Not all I think his name was Ray Mansfield a center with the steelers. He tried to make Butkus a cripple because he hated him so much.
Their was a story about Willis Crenshaw a back with the St. Louis Cardinals who tried to stiff arm Butkus. He got his fingers inside Butkus cage. Story goes Butkus actually bit off one of his fingers.
