While fans and the media have predictions about who the Eagles will sign and/or draft this offseason, there are three offensive linemen already on the roster that will be given a chance to make an impact next year.
1. King Dunlap, OT
The 6'8" seventh round pick from Auburn has a lot of potential. He was placed on IR last year, but I think that was more because he wasn't quite ready to play in 2008. However, the Eagles like projects. It has been said that if he put forth maximum effort his senior year, he might have been a first day pick.
I watched this guy when I went attended training camp in Lehigh. I believe he's the real deal, and with Juan Castillo overseeing him, he'll produce on the field. If not, he was a low risk project. Something to think about if Jordan Gross or Vernon Carey don't make it to Philly.
2. Mike Gibson, OG
A sixth round pick from Cal-Berkeley, Gibson was placed on IR last year with Dunlap, I believe for the same reason. I don't see him starting anytime soon—not with Todd Herremans, Shawn Andrews, Nick Cole, and Max Jean-Giles in front of him. But, as last year proved, who suits up is very unpredictable. He should be ready if called on.
3. Mike McGlynn, OG/OT
A fourth round pick from Pittsburgh, McGlynn is known to have a nasty mean streak similar to Jon Runyan. What people may forget is Runyan himself was a fourth round pick in 1996. McGlynn will be coming back from a torn hamstring injury come training camp, so that definitely is something to keep an eye on.
McGlynn is the one 2008 O-line draftee that suited up his rookie year, so some experience has been earned. There is a possibility that he could end up starting next season on the right side next to Andrews (I know nobody wants to hear that, but if Reid goes that route, remember this article).
These three guys are definitely under the radar right now. They may not quite be starting material yet, but even so, they definitely will give the Eagles quality depth on the offensive line, giving them a chance to look at other key needs in the draft.
