14. Barry Sanders, Lions, 1989-1998
Undoubtedly the most electric player in NFL history, Sanders was a threat to take it to the house every time he touched the ball. Sanders possessed a unique combination of quickness, elusiveness, and strength that may never been seen again. Despite playing behind a weak offensive line on a struggle team, Sanders still managed to become the first back in history to notch five 1,500-yard seasons. Frustrated with management and their inability to surround him with better players — which often lead to defenses ganging up on him — Sanders shocked the NFL community and retired in 1998 at the age of 30.
