Every time Mahomes got the score close for TT the defense would lay an egg and OU would score. The backbreaker in the game was the score OU got right before halftime and got the ball again after the half, only to score again...
Mayfield really changed his game after his freshman year at Tech. He was nothing but a turnover machine that year. He never grew up off the field though.
Mahomes has a better arm & a better attitude. I think he'll be the better QB in the long run.
