I expect the line to start out as Gilbert-Foster-Pouncey-Decastro-Adams next year.
I forget who reported it besides Douchette and Dushlac, but Haley is requesting more athletic O-linemen to run his scheme. They will re-sign Foster if he commits to getting in better shape. He needs to be more mobile.
The Gilbert part of that line is the concern because there is no Plan B. The better plan is to bring back Starks and let Gilbert and Adams fight it out for RT.
