IMO, it's past time to argue about Dak's advantages in Dallas at this point.
Unless he crashes and burns ala RG3 (and I don't see that in his game), the whole NFL, even including Dallas, and a lot of other draft people underestimated Prescott. And that's ok. Thank goodness the NFL isn't boringly predictable.
Our QB is Goff, and his success or failure is going to depend on him and on the new Ram coaches. It can never be proven, but I think most observers doubt that Jared Goff could have had Dak's season if only he had the Cowboy team and coaches around him.
zn is right. He was just too green. It's not really that debateable.
The question is where he goes from here.
McVay says Goff has the "traits" that you look for in an NFL QB. That is careful wording. Having the traits and being able to put it all together not the same thing.
Is Goff driven to succeed? Despite his laid-back off field demeanor, there is evidence and testimony that he is indeed driven, and a hard worker.
Sometimes that isn't enough. Sometime it is, if enough natural talent is there. Between the ears, I mean, since I'm not concerned about his arm.
How good is he at self-evaluation? Is he aware of his own flaws, and can he do anything about them? Part of my problem with the other guy was that I just didn't believe he even knew or wanted to acknowledge the areas where he needed to get better, and thus no improvement. But he started way higher and better than Goff has. Won't go any further on that, just a minor point of comparison.
We're so close now (weeks) from getting new data on whether Jared Goff is on a good trajectory, that to me, Dak Prescott is irrelevant to the conversation.
