Carr will take a red shirt year to learn the system more than likely, but TB might not be around if ND dips into the portal again next year for a QB. If he is smart, he will be just like a sponge learning everything he can from someone who has been there before.You can't plan ahead anymore with the transfer carousel. No one is going to stay a backup when they can start somewhere else. For example say Carr comes in 2024, can you predict Buchner would stay around to play with Minchey, Carr, AND whomever transfers in?
