6. Marshall Faulk
The most important cog of the Rams’ "Greatest Show on Turf," Faulk is, quite simply, the greatest receiving running back of all time. But although he averaged more than 63 catches per season in his NFL career, the seven-time Pro Bowler could also run, tallying seven 1,000-yard seasons. Remember, this is the player who took home the Offensive Player of the Year award in three straight seasons, most memorably in 1999 when he eclipsed 1,000 yards in both rushing and receiving.
5. O.J. Simpson
We know it’s hard, but put his post-football, um, hijinks aside and you have a legendary back. Wasted as a kick returner and decoy for his first three seasons in the league, Bills head coach Lou Saban finally turned the Juice loose in 1972. O.J. made the most of it with an explosiveness that helped him shoot through the line of scrimmage and into the open field, where his USC track skills took over. Best remembered for notching 2,003 yards in a 14-game 1973 season, Simpson had an NFL best six 200-yard games in his career, most of them coming for awful teams. (He made the playoffs just once in his career.)
4. Emmitt Smith
When you think of Emmitt Smith, it’s hard not to picture the over-the-hill back with gray in his goatee and a grinding desire to take over the rushing record. It finally happened on October 27, 2002 as a Cardinal, but the eight-time Pro Bowler was the heart and soul of a Cowboys team that won three Super Bowls, including in 1993 when Smith became the only player ever to win a rushing crown, MVP, Super Bowl and Super Bowl MVP in the same season. Yet, even though he’s the owner of a record 18,355 career rushing yards, your girlfriend probably still knows him best as a one-time Dancing With the Stars champ.
