Eagles depth chart: Which position on offense concerns you the most?

Now that the Philadelphia Eagles 53-man depth chart is finally here, it's time to revisit an important question: which position on the Eagles roster concerns you the most?

Here's a position-by-position breakdown of the Eagles roster, starting with the offense.

Quarterback

Sam Bradford, Mark Sanchez, Stephen Morris

Bradford had a great summer. Not only did he look great in practice and during the preseason (albeit in a small sample size), but he stayed healthy and never showed any signs of injury. He didn't miss a single rep in practice. IF Bradford can stay healthy, he could put up some big numbers in this offense. Sanchez had a nice spring but didn't look so hot in the summer. It's clear he's nothing more than a solid backup. Morris is the new guy who won't even be active on game day barring an injury to one of the first two quarterbacks. The 23-year-old could be a nice developmental guy to have for the future.

Running Back

DeMarco Murray, Ryan Mathews, Darren Sproles, Kenjon Barner

The Eagles are obviously stacked at this position. The combination of Murray and Mathews is a very strong one-two punch. These are physical, no-nonsense runners who punish defenders and grind out the tough yards. The Eagles got away from running the ball a little bit last season. They probably won't make that mistake again. Sproles will also get a few carries here and there but it seems the team is set on using him more often in the passing game. Barner won't get too many touches, if any, but he's proven his worth as a punt returner and a guy who can make plays in space. He's Sproles-lite.

Wide Receiver

Jordan Matthews, Nelson Agholor, Josh Huff, Riley Cooper, Miles Austin, Seyi Ajirotutu

Matthews is clearly the best player here. He's had a great summer. He's a weapon in the middle of the field working the slot. The Bradford-to-Matthews connection was unstoppable at times this offseason. Agholor showed this summer why he deserved to be a first round pick. He's flashed some real talent. He's incredibly shifty. The rookie still needs to work on some concentration drops before he can be relied on a full-time player, however. Huff returns hoping to improve upon a disappointing rookie season where he didn't play much. Huff looked good in practices but had a quiet preseason. He's kind of flying under the radar right now. Cooper is still around. In theory, he offers value as a blocker but he was a liability as a pass catcher last season. Perhaps the Eagles signed Austin to eat into Cooper's reps a little bit. The veteran is far from a playmaker but he's kind of like the new Jason Avant. Just a possession guy who runs good routes. Ajirotutu will make his living on special teams.

Tight End

Brent Celek, Zach Ertz, Trey Burton

Despite not being much of a receiving threat at this point, Celek is still the team's trusty blocking tight end. With the Eagles aiming to get back to running the ball more often, his value as a blocker theoretically increases. Still, the Eagles need to get Ertz on the field. The team has seen improvement in his blocking and he's obviously the more dynamic receiver. Ertz might be a little banged up to start the season while coming off a groin injury but he shouldn't miss significant time, if any. Burton is certainly a nice third tight end to have. He's a major contributor on special teams and he provides value as an offensive contributor as well.

Offensive Line

OT Jason Peters, OG Allen Barbre, C Jason Kelce, OG Andrew Gardner, OT Lane Johnson, T/G Matt Tobin, C David Molk, T/G Dennis Kelly, C/G Josh Andrews

Peters, Kelce, and Johnson are three starting studs. Outside of them, there are some questions marks. Barbre and Gardner aren't young but they don't have a ton of playing experience. For what it's worth, both guards graded out well in the preseason by Pro Football Focus. Barbre ranked 16th out of 146 guards and Gardner ranked 26th. Plus, guard is typically considered one of the least important positions on offense anyway. The depth behind the starters is questionable, however. Tobin struggled last season, and he's the top backup at every position except center. Molk might be serviceable as a backup center. Kelly is just a guy at most. Andrews is an interesting player because he showed some potential as a run blocker this preseason with PFF's fourth best run blocking grade by any guard.

Kicker

As I did last year, I'm lumping kicker into offense for the sake of this discussion.

The 23-year-old Cody Parkey has had a strange summer. The second-year kicker went five-for-seven in field goal kicks and also missed an extra point attempt in the first two preseason games. Then he sat out the last two games with a groin injury. He expects to be ready for the season and the Eagles only kept him as the one kicker on the roster, which seems to be a good sign. The Eagles are hoping these missed kicks were just a blip on the radar instead of a sign of more struggles to come.
