He has a phenomenal arm and runs the Walrus’s offense well. His inexperience and lack of ability to really understand a defense, and his reliance on first reads within the scheme, was on full display in the AFCCG. Not only was he embarrassed in the first half, but all of his big plays in the second half were well designed screens and misdirection plays. I don’t put a ton of stock in ESPN’s QBR, but they got that one right by giving him a very subpar grade.
He has the physical potential to be something very special...then again, Marino, Young, and Rodgers were also the “perfect prototype” as well. Maybe Favre too. It is possible for anyone to plateau or even regress, and it isn’t a given at all that experience builds a better understanding of the game. Right now Mahomes is very dominant but it isn’t because of his ability to read defenses. He plays checkers and it works due to his pure talent and supporting cast.
That said, I’d take him over any young QB in the league and he is really fun to watch.
