You're crazy...
Keller played LIGHTSOUT!!
He didnt make any mistakes all game and in my opinion the fumble wasnt his fault, the offensive line let the longhorns through.
Yeah i think Ganz looked really good and I am a huge fan of Joe Ganz but hindsight is always 20/20 and there was no reason whatsoever to pull Keller out of the game at any point.
Unfortunately Keller is probably done for the year. Looked to me to be a broken left collarbone the way he was holding his arm and how they wrapped it up on the sideline. Pure speculation though, cause i really hope he's not done for the year.
If Keller is out I have full faith in Ganz though, so at least there is no worries there.
