The OP is factually incorrect anyway. Dak has a better record as a starter against Washington than he does against Philly. He's 8-3 against Philly and 9-2 against Washington. That said, I think we need to come to terms with the fact that as a passer Dak is simply behind other QBs who have been raised up in passing systems with better passing coaches than Dan Mullen. Or whoever his high school coach was. Like I keep saying, in high school and college Dak was used a lot like a single wing tailback. He had a lot of games with 20+ carries. Which was great for his teams but did nothing to get him ready to play QB in the NFL. Then he comes to the NFL to be tutored by the greatness that was Jason Garrett... Yeah.. I know.
We have seen that when he is on Dak can throw the ball as well as anybody. He is deadly accurate to all parts of the field and he is one of the best if not the best throwers on the run that I've ever seen. But he can get knocked off kilter at times and it sometimes seems difficult for him to get back "on" when that happens. It's like when a pitcher loses his release point and can't throw a strike to save his life in the middle of the game. In most cases they can't get it back DURING the game and have to be pulled. Dak usually does but what typically happens is that by the time he pulls it back together his receivers have now gone into the tank and Kellen Moore, in his usual oblivious fashion, starts just calling any old plays from all over the play sheet without any rhyme or reason. And we know he isn't going to call a bunch of running plays until Dak can get back on track.. I mean you can't do that can you? I'm sure there's a league rule against it.
I think when Dak gets knocked off track the QB coach or Kellen Moore or Mike McCarthy need to see it and get with him on the sideline and work him out of it. There are key words that help you realign your technique in every sport at every position. So there has to be those for QBs too. Those guys need to whisper those words in Dak's ear on the sidelines between series.. even have him do some simple drills on the sidelines to get himself back aligned. The little hip wiggle drill, footwork drills, whatever it takes. I don't care if it looks silly on TV. Do we want to win the damn game or not?
