I agree that he's got a great shot, particularly since he is so young and talented. I think games like this one will help shape who he is and how he plays and how he leads his team. He's going to be there for a while, so if he wants to pull through tough games like that, when he has backups, he'll have to do it. Brady had some good teams in New England, but they weren't always all pro teams. He carried them through more often than not. Mahomes will have to do the same thing.
It's a shame they were so poorly coached in that game. The KC defense did nothing to help, but you'd have thought their offense would have changed things up in the second half.
