Howard Smith-US PRESSWIRE
Starter (LT): Demetress Bell
With Jason Peters likely out for the entire season, the Eagles will count on another former Buffalo Bill to man the left side. Bell is no Peters, but he's been working with the big fella during training camp and is sure to get a ton of attention from Howard Mudd to make sure he's at least up to snuff.
Starter (LG): Evan Mathis
While I'm personally not a huge fan of Mathis on the field, his five-year, $25 million deal guarantees his spot to the left of the interior.
Starter (C): Jason Kelce
Kelce got off to a ridiculously slow start last season, but came on strong at the end and seems to really have a grasp of the position and of Andy Reid's offense. If he progresses the way he should from his rookie to sophomore year, the Birds will be set at center for a while.
Starter (RG): Danny Watkins
Speaking of rookies off to a slow start, none started slower than Watkins, as he spent the first month of the season on the bench behind Kyle DeVan. Yes, that's right, Kyle DeVan. But once Watkins took the spot (basically by default) he was extremely solid and had an underrated year. I think Watkins quickly shows Pro Bowl talent and shores up the interior of the line.
Starter (RT): Todd Herremans
Thanks to injuries at right tackle, Herremans was thrown into a new position for all of last season. There were growing pains, but obvious signs that Herremans could catch on—and he did. His play towards the end of the year earned him a new contract and a starting spot.
Backup (T): King Dunlap
Odds are good that should Bell or Herremans go down, Dunlap will be the guy who gets the call to step in and start. Dunlap has played both sides and even started one game at guard last season, but his 6'10" frame makes him a less-than-ideal candidate to play on the inside. If Peters is able to return, Bell will be the primary backup on the left and Dunlap will be the No. 2 on the right.
Backup (G): Julian Vandervelde
The second-year guard will get a shot to be the next man up on the inside, but I'm still not convinced. He looked absolutely lost during the preseason last year and, for me, was a guy who didn't even belong on the roster. But Reid is loyal to his lineman and clearly sees something in Vandervelde to make him think he can be trusted to step in should Mathis or Watkins miss time.
Backup (C/G): Mike Gibson
Gibson comes back to Philly on his second stint with the Eagles. Gibson was an Eagles draft pick who got stashed on the practice squad but was signed away by the Seattle Seahawks. Gibson will likely be the primary backup to Kelce at center, but could also see time as a guard if Vandervelde looks as bad as he did last season.
Backup (G/C): Dallas Reynolds
Reynolds has gone from the obligatory BYU offensive lineman that Reid must carry on the roster to a legit backup who has worked his way up from the bowels of the depth chart. Reynolds might not dress for games very often, but Reid loves versatility and Reynold's ability to play all three interior positions will likely earn him a roster spot.
Backup (T): Dennis Kelly
The Eagles will likely want to keep two backup tackles on the roster, and the second will likely be the 2012 fifth-round pick out of Purdue. Like Reynolds, Kelly could find himself inactive for most of the season, and even off the team entirely and on the practice squad should Peters be able to return.
Sixth-round pick Brandon Washington will most likely find himself on the practice squad after losing out to the more experienced, and more versatile, Reynolds. However, seeing the opposite also would not be surprising.
Peters, as expected, will start on the PUP.
