LeSean McCoy enters the 2012 season prepared to share more carries after posting 273 attempts in 2011. Dion Lewis hopes to beat out Chris Polk and Bryce Brown to become McCoy's primary backup for the Eagles. “Yeah, I think it works better because sometimes I might be getting tired, instead of being selfish taking that rep, I think Dion deserves to play,” McCoy said after Thursday’s walk-through. “He’s a good player. You go out in the league and see a lot of teams who rotate and last year we didn’t rotate … not enough really so I think it will be a good year.”
