For me the list is Payton, Sanders, Bo, Smith and Peterson. If Bo or Sanders had kept playing who knows...
Smith had the yardage but I didn't find him exciting to watch. LT was more exciting than Emmitt.
I hope AP breaks the record, his work ethic is amazing.
I collect Bo Jackson, James Laurinaitis, PSA 10 RCs from the 80's and Ohio State Buckeyes to name a few.
