It's actually not me who's saying that.
Von Miller said that the tell was Stork's helmet bob. I am only quoting him, as well as what the article pointed out. He called it a tell, so I am doing the same. He said it was a tell that Denver was working with, in order to time the snap. The stills in the ITP article backs him up because it shows them (Denver) firing off the line while our OL was still set.
The ultimate point, however, was whether BB was a micromanager, and if so, he would have caught that. My argument is that he is not a micromanager, he hires people that he feels he can trust and just puts them in charge.
Just as he did with Flores, who he is not going to micromanage, if we are to judge by his history with Guge, who he fired at the end of the season once he had time to really review everything.
