OP - the challenge here is you have a HC who's spiraled downward his three years at Miami in the months of November and December with a 4 -10 overall record. Assuming the HC continues this performance, and at this time there's no reason to believe otherwise, you would be asking a true Frosh to come in and play lights out having to win 6, while losing 2 as the final four games you'd be staring at 1-3 (HC past performance) to aim for the 7 wins as you ask.
I don't see it with the current HC to have a Frosh QB prepared and ready to go against ND and couple weeks later UF. Better option is acquiring a vet QB that knows what Dawson is running, can make all the throws and has mobility to escape a collapsed pocket.
