I think rhythm is the overall most important thing. Once you can establish that, the offense can really get rolling. It all feeds into each other really, and once things get going it all snowballs.
Once you can establish rhythm then it comes down to timing of the plays, especially ones that you’re trying to set up for later in the game. I am not sure how aware people are of how tediously planned some plays are, going back to earlier weeks. There can be an arc of an entire season on certain plays.
One week you’re running a certain run out of a certain look and you know the opponent has seen it and will prepare for it. That’s when you work in your play action out of the same look the following week. That’s just a simple explanation.
But really it’s all about rhythm. We’ve seen the Pats run the same play over and over, even out of the same formation, when it’s working. When they find a weakness or vulnerability the pound it.
The Pats also run the same plays a lot, they just vary the formation to disguise it.
However we’ve seen plenty of times that they try to quick snap to catch the defense off guard or with too many men on the field and it gets snuffed out for no gain or even a loss. Sometimes I think they get a little bit carried away with that stuff.
