Quarterbacks aren't on the field at the same time, quarterbacks don't play against the same level defenses in the same game, and quarterbacks don't always benefit from the same level of coaching.
Water is wet and circles are round. And yet, we have to make judgements... or at least real men do in real world. They can't sit on the fence and go, "Hmm...your parents were more fortunate than mine, and you had a better 2nd grade teacher, so therefore...I can take all the money but very little accountability." Dak is supposed to be a coach on the field...that's why he got paid...he's not paid to go deer-in-headlights and then blame the coach. Had Dak taken $40-45mm/year...we wouldn't be having this discussion. But he demanded the bar be raised and so now it is.
