The point is, Dak played really nicely, especially for a rookie. But good gosh, he left so many plays out there, too. He doesn't have the confidence yet to stand in the pocket and make all the throws. Doesn't mean he won't, but he's not right now.
I saw so many receivers running free down field last year (I'm at all the games), and he chooses the check down to Witten for six yards. Nice play, but there was an easy TD to Williams or Dez if he'd just look upfield. He'll throw the deep sidelines, but the deep middle still looks murky to him. He doesn't like back shoulder throws (I really hope he's been working on those because that's Dez' greatest ability.)
If he can stretch the defense (like Romo did), Zeke will absolutely destroy teams for huge runs on a regular basis. They'd be indefensible. Truly. I don't know what possible defense you could call to stop us.
The Giants and Vikings squeezed the pocket and covered the short stuff, and Dak got really uncomfortable. That book is out. He's going to have to counter that approach this year every game, and I am certain he knows this and is working hard on it. It's coming. If he can, there will be big plays over the top to be had.
That's what I'm talking about. Notice, I didn't make a single point with "stats". They just don't matter that much at all. I pay attention to three stats: 3rd down conversion %, turnover margin, and final score. That's it. The rest are lies.
