What We Know: LeSean McCoy is an exciting rookie who has proved that he can handle the duties running the ball and receiving it out of the backfield. McCoy gained 84 yards on 20 carries in his start against the Chiefs, and he also showed that he can run the wildcat effectively. He's also been a surprisingly effective blocker in blitz-pickup. Leonard Weaver is a physical run blocker who can open up holes for any running back and he also has very good hands for a fullback. Eldra Buckley is a downhill runner who can contribute on special teams.

What Needs To Be Resolved: The health of Brian Westbrook. When at the top of his game, Westbrook is one of the most dynamic players in the game, and contributes to the offense with his running, receiving, and blocking. Westbrook also showed the ability to run the wildcat effectively, but his impact in the long run will be determined by how his body holds up. Also, can McCoy protect the ball over the course of the season? He's been prone to fumbles because he tends to carry the ball away from his body. It's something he will continue to work on, but it must get better soon. Finally, will Leonard Weaver get looks as a short-yardage ball-carrier? Head coach Andy Reid has talked about Weaver's reputation as a reliable short-yardage runner, when will we see it in action?
