All season long Dak has benefited from absurdly wide open receivers... heck, even in last night's debacle he got another one, a busted coverage play where Williams was so open Jerry could have came down and hit him. Cole Beasley in particular has been unbelievably open all season long, and Witten has had entire games where the defense seemed to not know he existed. It's no coincidence these guys are our two leading receivers... and it's also no coincidence they've been bottled up lately.
Dak is a dink and dunk game manager. If you give him all day in a clean pocket and large windows to throw to, he is adept at reading coverages and will beat you with short, straight line throws. If you ask him to make any other kind of throws with any kind of regularity, especially into coverage, he is going to look worse than Osweiller does in Houston. It's not just going to magically get better, that's who he is. And let's not pretend the Giants are an ace defense like the Vikings. They are good against the run, but they came into last night's game in the mid 20s in pass defense.
