I wish we had a back like Marshawn Lynch, hardly ever goes down on the first hit, keeps fighting to the end. I know his kind is hard to find. In the old days you had a good many around that would fight to get all the yardage they could, Csonka, John Riggins, Walter Payton, Earl Campbell, etc. Man, miss the good old days.
And add Ricky to the list. I used to love seeing him lower the boom on some unsuspecting db or LB, boy could lay the wood.
