which they may very well do, but to me if you do you are closing the door kinda on Corbitt being the plan. If he comes in he'll have to take snaps away from Corbitt, IF you do that you may as well hand the job over to him. Being a starting center with playoff experience on top of regular season play time he would be out and out our center. Yes Corbitt could learn from him, but IMO Corbitt is considered 1 of our top linemen...move him back to his old spot?
That would maybe be the-better move,maybe not..... in doing so you haven't answered the lingering question of if Corbitt could be the long term answer to be our center 2021 and beyond....It would IMO basically delay the need to get that spot really nailed down and worry about our next LT.
