You are not completely wrong about Dak. Despite the perfect Passer Rating, he did not have a perfect game (albeit, he played REALLY well).. Still, you are missing that fact that he made some very good throws in this game.
Yes, he was slightly behind receivers a few times and his guys made him look good on those plays. To me, I've already seen a big improvement on a number of things that I've been harping on Dak over the last few seasons. He seems to be anticipating his throws better and trusting his receivers and his reads. His long passes to Gallup were among the perfect examples of this. Cobb may not be quite as quick as Beasley, but his speed gives us a new wrinkle in the slot and Dak exploited it evey chance he got. Outside of an uncharacterisitc drop, Copper looked terrific too.
Yes, I know it's one game and the "throw behinds" are a bit disconcerting, but I think this season they are more about receiver timing than about "getting the ball out late" like in past seasons, as he was not missing by much on those throws against the Giants (giving his receivers a chance ti make plays). I think this is eminently correctable and with the talent at the position Dak has to work with, I'm highly optimisitc that Dak will continue to improve in this regard. As far as "intangibles, work ethic and leadership" all of the great ones had or (in the case of a few still playing) have it. His teammates in the huddle (and even on the other side of the ball) believe in this guy and that's good enough for me
Yeah, he won't have games like this every week, but I think he's gotten better and I believe that he will continue to improve his ball placement over the course of the season. Based upon the guy I saw on Sunday, I've gone from hopeful but somewhat skeptical about Dak to a cautiously optimisitc Dak believer. That is based on what the eye test told me about Dak in the past and what my eyes are telling me about him now.
