It's Breece and it's not even close. As great as Hutchinson and Kolar did, Breece scored at least one touchdown in every game and was unstoppable when Manning wasn't quick to give up the run too early.
I know he didn’t earn first team Big 12 honors like some of the other players that have already been mentioned, but Brock Purdy is still the leader of our offense and deserves a shout out in this thread.
