Jason Peters and Dennis Kelly have both missed time at practice recently, and the Eagles did some interesting juggling to account for those injuries. Lane Johnson moved from RT to LT, Todd Herrmans kicked out to RT, and Danny Watkins moved in at RG. Evan Mathis and Jason Kelce stayed put at LG and C, respectively.
After practice yesterday, Chip Kelly talked about the OL shuffle. "If we were going to play a game, we're probably going to go with our best tackle combination," Kelly said. "So, for us to do that, then Lane needs work at left tackle, and Todd needs work at right tackle." So, instead of saying in the Redskins game, hey, we've got to move Lane, but he's never taken any snaps over there, we had planned all along at getting Lane work at right tackle and left tackle. We had [also] planned to get Todd some work there.
"If it ends up being Dennis [Kelly], Dennis may feel more comfortable playing right tackle, it may be a one‑person move, where, let's move Dennis into right tackle and Lane over to left tackle. So we're just making sure as you look down the road, we have some contingency plans on how it works. The versatility that Lane brings us brings us the ability for a guy that can play both tackles and to be honest with you, that's rare. There are some guys that are legitimate right tackles and finding tackles in this league is very difficult. That's one of the things that looking at him in the draft, here's a guy that can do both."
Based on Chip Kelly's above comments, it seems fairly clear that Dennis Kelly will not be playing LT off the bench, unless there's a scenario in which both Jason Peters and Lane Johnson are injured. And even if both of them got hurt, the Eagles may opt to slide Herremans over to LT, with Kelly filling in at RT. In other words, ignoring who wins the backup center job and including just the 5 starters plus Kelly and Watkins, the OL depth chart may look something like this if the Eagles think Herremans is a better OT than Kelly:
