"What can a 10-degree difference in the way an offensive lineman points his foot tell you about the upcoming play? The Broncos are one of a handful of teams who believe such minutia can tell you a whole lot, which is why they’ve gone to great lengths under coach Gary Kubiak to educate players in yet another realm of growing specialization in the NFL.
The Broncos employ two unheralded assistant coaches whose job descriptions are a closely-held secret. It boils down to this: Find the tells. Does a certain offensive tackle divulge run or pass with the placement of his feet? Or does a quarterback tip a play with a simple hand gesture? If so, Kubiak would like his players to know about it..."
I wasn't aware they were doing it but it makes a whole lot of sense. Where in life can't you succeed more often through a better awareness of your situation and all things that can impact it?
I can recall when most of us though that like Mike Singletary, Mike Brown would also end up coaching because he was also such a student of the game. Why wouldn't you want to use every tool you have at your disposal to gain an advantage. Apparently two of the Pats best defensive players, Chandler Jones, and Jamie Collins are no longer Pats simply because they wouldn't put the time into film study.
If you play high stakes poker you know you're playing the others at the table and not your hand so looking for patterns or tells is the difference between winning and losing. When I caught fast pitch for years I would study a batters stance and his swing plane along with his adjustments to certain pitches so I knew which pitches he couldn't handle at all and which he'd pull or couldn't pull and them I'd call the game and position the defense accordingly. I love analyzing stuff like that.
