Locks: Jason Peters, Todd Herremans, Jamaal Jackson, Danny Watkins, Ryan Harris
On the Bubble: Jason Kelce, Evan Mathis, Mike McGlynn, Winston Justice, King Dunlap, Austin Howard, Fenuki Tupou
The locks should be in the starting lineup come Week 1, while some of the backup positions still have competition. Kelce, Mathis, and McGlynn are also favored to make the team. Kelce is a favorite of new offensive line coach Howard Mudd and has provided unexpected competition for Jamaal Jackson in camp.
In Mudd's eyes, Kelce is similar to Colts star center Jeff Saturday, a smaller, more athletic lineman. McGlynn filled in well at center last year after Jackson suffered a season-ending injury, and can also play guard.
Mathis is a capable veteran, and over two years and 700-plus plays with the Cincinnati Bengals did not give up a single snap.
This leaves a void at tackle for the Eagles, as all three of their backups play guard. In addition, their starting right tackle, Ryan Harris, who is charged with protecting Michael Vick's blind side, sat out Saturday's practice with back spasms.
Winston Justice, last year's starter at right tackle, will most likely remain on the team, despite his large contract, though he will presumably begin the season on the PUP list.
Dunlap and Howard are serviceable, but inconsistent players. Both had their ups and downs in the first preseason game against the Ravens, though Dunlap performed slightly better. Tupou is another option, though he is unlikely to make the team except in case of injury.
Prediction: Jason Kelce, Evan Mathis, Mike McGlynn, Winston Justice, King Dunlap, Austin Howard*
