QUARTERBACKS: close call but - Joe Montana
RUNNING BACKS: Walter Payton and way ahead of others
WIDE RECEIVERS: Jerry Rice no question
DEFENSIVE LINEMAN: difficult call - Joe Greene
LINEBACKERS: Dick Butkus absolutely
DEFENSIVE BACKS: not sure
I would put Sweetness number 1 for durability, and considering the fact for most of his career he didn't have decent offensive lines to work with. Scary to think what he could have done with a decent OL.
