This is a very interesting comment for me. I have long believed that great coaches are great semanticists.
We so often hear about how important "communications" are in the success of the both the offense and defense. So clearly, language is a key element. Every system has its own "language" each as different as Chinese is to English. So one of the factors in being a successful coach is having the ability to give a lot of information in the FEWEST words possible. Believe me, given how complex offenses and defenses have become, this can be a daunting task.
You can't have players "thinking" on the field. Responses to what is called has to be instantaneous as well as purely reactionary. Its a lot easier said than done. Don't doubt for a second that part of the reason for the consistent success of the Pats is that they're all speaking the same language, and have been for a long time. But even then you have the need to parse that language into its most simple form. Its almost like creating an algorithm that speeds up a computer program.
