I think one of the underrated aspects of a QB is how bad they are when they/the offense is struggling. So they cost them the game? Are they completely useless? Do they find enough to figure it out for those two minute drives and win down the stretch?
That seems to be a major difference between a guy like Ryan and a guy like Brady. Haven’t seen a lot of situations yet from Mac, and it’s too early to tell. But certainly those games where the running game stalls and the defense has taken away your best options, is a big test.
