I'm not opposed to Tom moving to Center but I think it's easier to find a league average center in the mid rounds than it is to find a Right Tackle. You can probably get the kid from GA in 3rd or 4th round and he is 4th or 5th rated center in the draft. How many tackles that teams pray will be as productive as Tom will come off the board before that? 15?
If we think we got a guy who can do what Tom did at RT, move him and upgrade. If not, draft a center and tackle to groom.
