Here's the bottom line for me. We were 12-1 the one year he didn't start a majority of the games. While he helped in a couple of those games, our 2012 record shows that his impact was clearly vastly less important than people make it out to be.
I think he was quite important. Here are the games that he helped us win:
Purdue--most likely going to OT against Purdue with 0 momentum if not for Rees. Who knows, maybe Golson commits another turnover like the last drive and it's Purdue kicking the FG to win at the end.
Michigan--Golson was lost from the start. The D had more to do with us winning, but I don't see us winning that game with EG and Hendrix. We needed someone to play mistake-free and get a drive or two going.
Stanford--his 2 drives were a game-tying FG and a go-ahead TD in OT. In the rain. Golson already had a couple turnovers this game. Can you imagine Hendrix coming in and saving the day when Golson had his concussion?
BYU--Tommy played the whole game. Again, we're not winning the game with Hendrix in there playing 4 quarters, especially not against last year's BYU defense.
Honorable mention: Tommy playing one play against OU and converting a 3rd and long. We're running a draw there with Hendrix in the game.
IMO we're an 8-4 or 9-3 team last year if we're playing with Golson and Hendrix as our QBs.
