So much of the Philadelphia Eagles offense goes through running back Brian Westbrook basically because he can do so many things. He can run the ball inside the tackles, but has the speed to get to the outside as well. He catches the ball very well out of the backfield and can even line up as a receiver at times. And he makes things happen regardless of how quarterback Donovan McNabb gets the ball into his hands.
On the season, he ran the ball 233 times for 936 yards (4.0 YPC) and nine touchdowns. He also caught 54 passes for 402 yards and five touchdowns. And he only lost one fumble all year.
Obviously those numbers aren't among his career best, but he was slowed by injuries earlier in the season and missed a couple games because of it.
