i think Fromm had a fantastic season. freshman QB, 5* expectations, had to come off the bench, and he executed what they wanted him to do, to damn near perfection.
i think you can give him A LOT of credit.
that said, when you talk about 2017 UGA, and why they were successful, it's Defense, Running game #1 and #2 at teh top of the list. and having Fromm be who he was, is probably a very close 3rd.
i don't think Fromm makes a huge difference on the 2017 Vols, maybe we get to 6 wins and go to a bowl. but he doesn't take TN from 4 to 8 or 9 wins.
likewise, i think JG would have been better on the 2017 UGA team, and probably could have won the East. i don't know they win the SEC Title game or go to the playoffs with him. but 10 wins and a division title, and a NY6 bowl? yeah, i could see that.
we had a pretty bad team when it was all said and done last year. UGA had a really really good team when it was all said and done. and neither was defined by the QB.
