I'd like to point out that Jim Kelly called his own plays at the LOS, often in a hurry up mode, seldom with a huddle. Of course they didn't need to run too many different plays because they were so good.
Those 5 Cook runs in a row are the thing that irritates me the most about the Houston game. It's just incompetence. But Allen also needs to know that he should either audible out of dumb calls or call timeout in those high leverage situations. He is the most important guy in this entire organization. He has that latitude and responsibility.
