Man Up: What went wrong for Eagles' offense?

Where to begin with the Eagles' offensive struggles against the Cowboys?

We go player-by-player like we do every week. Enjoy.

Donovan McNabb - After turning in one of his best performances of the year in the first half against the Broncos, McNabb has struggled in his last six quarters. I know some will point to the lack of balance on offense, but the Eagles had opportunities for big plays in the passing game and just didn't get it done. The one he would like to have back is the deep ball to DeSean Jackson early in the second quarter. McNabb overthrew his receiver, and it also looked like he turned Jackson around with the pass. He struggled with the crossing routes throughout, throwing behind Jackson and Jeremy Maclin. The fumbled snap was huge, and after viewing the replay, it was a little low, but certainly one that McNabb could have handled. McNabb made good reads and took shots deep, trying to let his receivers make plays. But was just off-target all day, and his receivers weren't able to help him out.

Leonard Weaver - Two weeks ago, he had a season-high 19 touches against the 49ers. On Sunday, Weaver had just one carry for 2 yards and no receptions. He was on the field for just 16 snaps. That's no good. As a blocker, Weaver was solid, chipping and picking up blitzers multiple times to give McNabb time. He had a drop in the third, but there was no room on the play anyway.

Brian Westbrook - He was on the field for 28 snaps, carrying five times for 17 yards. The 8-yard run in the third quarter was his best of the day. The Eagles used Westbrook in a variety of ways. He was split out wide on multiple occasions, finishing with four catches for 20 yards, including a nice 11-yard gain. And he was outstanding as a blocker. Westbrook was flawless, chipping and picking up blitzers throughout. His blocks gave McNabb time on several throws, including a 25-yard completion to Brent Celek in the second quarter.

LeSean McCoy - McCoy played more than Weaver, but less than Westbrook, getting on the field for 19 plays. A season-low one carry to go along with two receptions. It looked like he tripped on the screen pass in the first. Like they did with Westbrook, the Eagles split McCoy out wide at times. As a blocker, he was called for holding in the fourth.

Jason Peters - As a blocker, Peters did a good job, keeping DeMarcus Ware away from McNabb for most of the day. He got beat once in the fourth quarter, but that was pretty much it. Peters got the better of Ware in both matchups this season. However, a pair of penalties from Peters hurt - a personal foul for hitting Mike Jenkins out of bounds and a false start in the second quarter.
