Could Dak have played better? Sure, no doubt.
But I went back and watched the highlight film. Why did the Texans win the game? It wasn't because of Dak's shortcomings, that didn't help but what happened to cause the loss was:
1. Watson should have been sacked at least 5 times. EVERY time, he was able to evade the sack, and throw the ball away or to an OPEN receiver.
2. Cowboys secondary could not tackle Hopkins. He's a great receiver, he slipped through tackle after tackle, he took an 8 yard throw and ran it for 20-30 yards on multiple occasions.
3. Zeke ran the ball, once again, only 18 times in regulation. Was always a close game, it's not like it was a blowout and the Cowboys needed to score quickly. Last game he got the ball 25 times and guess what? Cowboys WIN. Stupid coaching (again).
4. Failure to go for the 1st in OT. The Cowboys were doing pretty well, both defenses were tired, and you have a 235 lb qb and 225 rb, USE THEM. Multiple ways to get one yard, Dak hadn't been stopped at all on any runs, Brady sneaks for first downs every game, usually several times, and is successful nearly every time. It's NOT THAT HARD>
5. Gaping holes for the Texans rbs to go through, often times were barely touched. The ypc is low because of several tackles for a loss but many runs they had clear sailing.
In short better play by Dak in this game may have won the game, but in future games, the above shortcomings will still result in losses.
Quarterbacks aren't the only guy on the field, Dak doesn't have the team around him, at this time, to win many games, even if he plays much better. Just saying blaming Dak for all of the Cowboys' losses isn't helping anything...
