It's a loaded question, Spence. If, by bring back, you mean tender a contract than I say yes. He will more than likely be a Restricted Free Agent and I would be seriously upset if they let him get away without taking advantage of some compensation.
Beyond that, I think it depends on who the Head Coach is and what he wants to do.
At the moment, I am inclined to bring him back regardless. Worst case is that the Skins draft a guy in the 1st round and the two compete in the camp. If they don't use that 1st round pick on some offensive line help in the off season the chances are that they will need two QBs to make it through the season anyway.
If someone picks up Campbell's tender, the Skins can either match or run with a 1st and 3rd pick which sure can't hurt the rebuilding effort.
FYI - I would do the same with Rogers. A tender worth at least a 1st and 3rd rounder...
