IMO, that "if" is such a remote possibility, that it appears you are grasping at straws to defend an already suspect position.Because it could change the direction of who you acquire and who you draft this year and next. What if the next head coach feels his QB is in this years draft 1st or 2nd round? You’re basically forcing me to make Tua our franchise qb.
Besides that, I don't see any "must have" QBs in the upcoming draft, and if a perspective hire tries to tell me otherwise, I don't want him so no big loss.
The GM runs the franchise in the long term. The HCs job is one season at a time. If they can't stay in their respective lanes and both pull the same direction, it isn't going to work anyway.
