O.J. Simpson, Buffalo Bills
If there was a Hall of Infamy, O.J. Simpson might be at the top of the list.
Emmitt Smith, RB, Dallas Cowboys
The NFL's all-time leader in rushing yardage and touchdowns is most certainly a notable omission here. Emmitt Smith was great, but he didn't bring the electricity like Barry Sanders or plow through defenses like Jim Brown.
A good deal of Smith's success can be attributed to the players around him, not the least of which played on his fantastic offensive line.
Marcus Allen, RB, Oakland Raiders and Kansas City Chiefs
There are too many great running backs ahead of him.
Kellen Winslow, TE, San Diego Chargers
Before Antonio Gates or Tony Gonzalez, there was Kellen Winslow.
The San Diego legend was known as the greatest tight end in NFL history, a title now likely belonging to the still-active Gonzalez.
Gene Upshaw, OL, Oakland Raiders
There was simply no room for Upshaw here.
Bart Starr, QB, Green Bay Packers
Bart Starr was certainly one of the best quarterbacks in NFL history, leading his team to five NFL championships throughout his illustrious career. He didn't put up numbers like some of his peers at the position, however.
