If I were the Krafts, I would have a rigorously honest and private conversation with Drake Maye before the end of the season, the sole purpose for which would be to determine which coach - TC, AVP, whoever - has actually been of the most use to him in his development. I do not think this is the sort of conversation one could usefully have with most 22-year-olds, but I think Drake's really remarkable honesty and purposefulness make it a workable approach in his case. I would place very significant weight on his response as I decided what changes if any to make. If he credits primarily AVP and expresses a wish to continue with AVP as his mentor, I would, given what I regard as AVP's limitations as OC/play caller, offer AVP essentially the QB coach position, which he can choose to accept or not. If it is TC or somebody else whom Drake cites as most valuable to him, I would hire/retain that person as QB coach. I would then - asap - begin work to to secure the services of a more skilled, cutting-edge and experienced OC. We may have something valuable building here, and there is no need to be so prissy and squeamish about putting in place a coaching/GM team worthy of Drake's and eventually the team's potential.
I won't rehash my take on Mayo, which is basically simply that his hire was a mistake, that the hiring process was a joke, and that the Krafts should set aside their irrelevant personal affection for him and get an experienced, likely offensive-oriented, replacement HC.
I would fire Wolfe immediately.
