Aaron Rodgers won a SB leading the league with guys on IR.
Brady routinely plays with #2 WRs
While I get and agree with your premise, most other QBs don’t have such a drastic fall off when things go awry around them.
We’ll see this year if his accuracy issues are better. They likely won’t be totally fixed because he has a long way to go.
Glad you bring up Aaron Rodgers. I used to use him as an example when defending Tony Romo when his haters used to claim Romo wasn't good enough to carry the team to a championship. The rebuttal to that claim was no QB did and it still holds true.
Aaron Roders is a great QB, no doubt. But if you look at that SB run, he needed the defense to intercept the ball in the corner of the end zone to prevent a game winning TD drive by Vick and the Eagles in the WC game. In the NFC Championship game he was horrible. The defense carried him or else GB may have lost to the 2nd and 3rd string Bears QB's. In the SB he played well but still got huge plays from the defense to include a pick 6 and critical fumble recovery when Pittsburgh had taken the momentum in the game.
I get the desire to have a better QB than Dak. I don't get the desire for wanting a QB to be able to "carry a team to the championship". We have had a great QB that couldn't carry the team to a championship. Why do we want Dak to do it if Romo never could?
We need a team which makes plays when they need to in order to win games, to include the Quarterback.
