Centers:

Can Nick Cole hold his own at center?
This is the biggest problem area for the Eagles offensive line. With Jamaal Jackson expected to miss all of training camp and some of the regular season while rehabbing a torn ACL he suffered on December 27th, all signs point to Nick Cole to start under center. Cole took over for Jackson at the end of last season and struggled immensely down the stretch. A lot of his problems have to do with his small stature, as he is only six feet tall.
With the center position being relatively thin, Cole will be competing primarily with Mike McGlynn and A.Q. Shipley. McGlynn was taken in the fourth round of the 2008 draft by Pittsburgh but has failed to successfully break into the league. His main advantage when comparing him to Cole and Shipley is his size. McGlynn stands at 6-foot-4 whereas both Cole and Shipley are the two smallest offensive lineman. Shipley is a product of Penn State football, where he was an All-American in 2008 and was awarded the Rimington Trophy for best center in college football. Similar to McGlynn, he has yet to make an impact since being drafted in 2008.
I don’t think that Cole has this position locked up in the least bit. He showed glimpses of being a capable starter, but also struggled in big situations. With still a lot to prove as a starter, Cole is going to need to be in tip top shape come Monday to protect his starting job until Jackson’s knee is healed.
Guards:
Both Todd Herremans and Stacy Andrews are going to be vital to the success of the Eagles offensive line. They are both coming off of very mediocre seasons (to say the least), but are two of the most experienced players on the team. Herremans has not been the same since his foot injury and there are still a lot of concerns that it continues to hold him back from his fullest potential.
Now that Stacy’s brother, Shawn, is no longer a distraction to the team, Stacy is expected to make a big comeback in 2010. He signed a contract in February of 2009, but missed the regular season while rehabbing his knee after surgery late in 2008. With him healthy opposite of Herremans, the Eagles add a lot of experience and reliability on the line. If Andrews ends up underperforming in training camp or continues to deal with injury problems, expect Max Jean-Gilles to make a run at a starting spot on the line.
Tackles:

Will Jason Peters get support from the rest of the line?
Fresh off a Pro-Bowl season, Jason Peters is probably the most reliable member of the offensive line. Even though he suffers from “happy feet” resulting in a number of false start penalties, Peters is very experienced and his accolades speak for themselves. Peters is not the person that worries me, but rather the man that lines up on the opposite side of the line as him—Winston Justice. Every time I hear his name, I can’t help but immediately think of the painful images of Osi Umenyiora getting past him every play in 2007. However, the Eagles think that he is ready to be a top notch starter, hence the 4-year $21.3 million contract he was given in the offseason.
Even though I think Peters and Justice have their starting positions locked up for the regular season, there is still a good amount of depth at the tackle position in King Dunlap and Fenuki Tupou. Both Dunlap and Tupou are very young and don’t have a ton of experience (Tupou spent most of last season on the IR with a chest injury), but they have worked hard in minicamps and have been in great condition heading into Lehigh.
Defensive Line
The defensive line is the unsolved mystery of the 2010 Philadelphia Eagles. It was the most troubled aspect of the 2009 Eagles team, thus making it Andy Reid’s primary focal point during the draft.
Defensive End- Trent Cole, Juqua Parker, Brandon Graham, Daniel Te’o-Nesheim, Darryl Tapp, Ricky Sapp, Victor Abiamiri, Eric Moncur
Reid used his 13th (Brandon Graham), 86th (Daniel Te’o-Nesheim) and 134th (Ricky Sapp) picks all on defensive ends in the hopes that one of them will be able to be the future Trent Cole of the Eagles. All three of these players are not the biggest guys at their position, but certainly can pose a threat with their speed and agility off the line.

Trent Cole needs someone to compliment his skills
Speaking of Cole, he is coming off is best season in the NFL, recording 12.5 sacks and was one of the tops in the league in tackles for losses. He was elected to his second Pro-Bowl and was the most consistent player on the Eagles defense. Unfortunately for Cole, he has yet to find a companion to take pressure off him from the other side of the line. Darren Howard failed to make an impact the last few seasons and Jevon Kearse was one of the biggest busts in Philadelphia history. Andy Reid is hoping that former Michigan Wolverine Brandon Graham can be that guy. Graham earned second-team All American honors at Michigan in 2009 and recorded 29.5 sacks and 56 tackles for losses in his four year career. He is expected to compete heavily with Juqua Parker for the other defensive end position.
Parker is certainly no pushover heading into training camp. He is coming off his best season for the Eagles in 2009, recording eight sacks and picking up a lot of the slack for the underperforming Darren Howard. He is entering his 10th season with the Eagles, which makes him the second longest tenured Eagle behind kicker David Akers. He is nearing the end of his five year deal signed back in 2007 and will be fighting hard to keep his starting spot.
Other defensive ends that have big potential come Monday are Daniel Te’o-Nesheim, Ricky Sapp and Darryl Tapp. Both Te’o-Nesheim and Tapp have gotten a lot of snaps in the nickel formation during spring practices. They are more known for their pass rushing capabilities, which could end up being useful in shuffling them between defensive end and defensive tackle. Ricky Sapp also has a lot of versatility in his style of play and could even get some snaps as a linebacker at training camp. Reid figured that by drafting smaller guys with speed he will be able to shuffle them around and make the best possible depth chart come the regular season.
In case you were wondering, Victor Abiamiri is still continuing to rehab from micro fracture surgery that could keep him out for awhile.
Defensive Tackles- Brodrick Bunkley, Antonio Dixon, Jeff Owens, Mike Patterson, Boo Robinson, Trevor Laws

Patterson is going to need to be a leader on the defensive line
With a lot of young talent being moved in and out, the tackle position will certainly be an interesting scenario to watch unfold. Brodrick Bunkley and Mike Patterson are clear favorites to keep their starting jobs, but Trevor Laws, Antonio Dixon and a lot of the young guys are always breathing down their necks. Laws has battled injuries for the past two seasons and was inactive for five games last year, but finally seems to be healthy for once heading into training camp. Dixon played in every game for the Eagles last season despite making a minimal impact.
Rookies Boo Robinson (To Kill A Mockingbird anyone?) and Jeff Owens have a lot to prove to Andy Reid to make the final roster. With a deep defensive end core that have a lot of crossover players, Robinson and Owens are going to be under the microscope every day. Robinson was signed as a rookie free agent by the ‘Birds after compiling 145 tackles, 12.5 sacks and two interceptions in 52 games for Wake Forest. Owens was taken in the 7th round of the 2010 draft and has a great combination of speed and power. He is only 6-foot-1 but weighs over 300 pounds and has quick feet off the line.
Overall, much of the success of the Eagles 2010 season relies heavily on the defensive line. One of the biggest holes in the Eagles’ game last season was the lack of pressure on both the quarterback and on the running back (if you want proof just watch both of the Dallas games to close out the season). Trent Cole is searching for someone to take some weight off his shoulder on the outside while Mike Patterson and Brodrick Bunkley are hoping to get some support in the middle. With how much time Reid put into drafting these players, there has to be a few gems in his stack of draft picks.
