What Mayfield and Mahomes did was against Big 12 defenses too and they appear to be making the transition. These Big 12 QB’s are for real and their offenses are part of why those defenses statistically were so bad. Big 12 has more focus on their offenses and prolific QB’s. Will Grier from West Virginia is another one I’d be looking at. And Steinham from Auburn who was originally from Baylor another. Big 12 is becoming a cream of crop for QB’s because of their prolific offenses which is an attraction for this football fan and apparently the NFL.
