No it isn’t sustainable and it’s why they are so inconsistent. If Watson were in a real offense, he’d be up there with Mahomes.No doubt about it they did .... but ask yourself how much of that was off schedule magic and is that sustainable ?
You want to know why Watson holds onto the ball. Watch the all22. Numerous occasions the Texans had 4 receivers in the pattern and they were all at the same exact depth downfield, almost in a straight line, and they were all covered. How do you design plays where everyone runs 10 yard routes??
Watson holds onto the ball because there’s nowhere to go with it. These routes are garbage, the design of the plays are garbage. Play calling don’t make a bit of difference if the plays you have to choose from are flawed.
