I disagree with Cam, especially for Dak
That's the thing. Quarterback is a position that you don't need to have highlight film material to be considered good. Cam Newton, Michael Vick, have some great highlights, but they're hardly considered great QBs. Tom Brady has zero highlights but people consider him the greatest of all time.
Cam Newton could make this spectacular happen, but he's also make the simple look very hard. He would miss easy throws at times because he was not very refined as a passer. Josh, Allen makes spectacular plays at times also, but he also makes the simple look difficult. Zach Wilson can do the spectacular too, but makes easy stuff look hard.
When I think of game manager , I think of Trent Dilfer, Jake Delhomme before the Super Bowl , Jimmy G on the 9ers, Tom Brady in his first year starting. I look at them as guys that the team feels need to just not turn over the ball and make a few throws here and there on their down while they rely on their run game and defense to keep things manageable.
