Any time a running back can be mentioned in the same sentence as the one and only Jim Brown, it goes without saying that he's done something significant. And if that running back is Adrian Peterson, it can only be assumed that he is continuing to build on what is already a compelling case for the Pro Football Hall of Fame.

After taking over once again as the Washington Redskins' primary running back in place of the injured Derrius Guice, Adrian Peterson punched it in for the Redskins' first touchdown against the Dallas Cowboys, scoring the 107th rushing touchdown of his NFL career. Peterson's touchdown moves him to fifth on the NFL's all-time rushing touchdowns list, surpassing Jim Brown's mark of 106. Peterson is now behind only Walter Payton (110), Marcus Allen (123), LaDainian Tomlinson (145), and Emmitt Smith (164).

Peterson once again getting into the endzone comes only one week after he was rendered a healthy scratch by the Redskins, who opted to leave the Oklahoma Sooners legend-turned NFL great on the bench while Guice made his NFL debut. However, thanks to yet another knee injury and subsequent surgery, Peterson had once again taken over as the Redskins' mail carrier. And for head coach Jay Gruden, Peterson's professionalism over Week One is a mercy.

"Nobody's happy if you're the backup or not dressed, but you are on the team, and when your number's called you roll," said Gruden earlier this week. "Adrian's a pro, and I feel very good if his number's is called this week, he'll be ready to go and play very hard and he'll be Adrian Peterson."
