So I was watching one of those break down videos on nfl.com where they essentially break down the offensive/defensive plays that stood out during the game. One that I really like was when the Saints ran a play where they get ready to run a screen play, however, its just a decoy to get Jimmy Graham open. The defenders bite and he's wide open.
So here's my question: Can offensive coordinator, seeing a play they like, use a play by other offensive coordinators for example the one I just mentioned or is there an unwritten rule in the nfl that prohibits that. I guess a good argument to this would be if each offensive coordinator patented a play then almost every offense in the league would be very predictable and ineffective. But I'm talking about the really unique and iconic plays that make people say that only so and so coordinator would run that. I'd really love to see KG run that play. Either he already has and I haven't noticed or simply has not.
Would it be something like when back in the 80's Buddy Ryan introduced the 46 defense? That defense was almost exclusively used by him. But then as time progressed and other defensive coordinators saw the effectiveness of it, they accepted it into their repertoire and after a while became a normal defensive formation.
Just a curious question from a football newbie who wants to increase his understanding of football.
