That being said, Chadman is not convinced that this current trend/theory is necessarily correct in all it's beliefs. The NFL is very copycat, so it seems most teams feel this way. But it just needs one team to be able to dominate on the ground through the running game, or on Defense, be so stifling in run defense & capable of turnovers in pass defense that suddenly other teams will want to 'be like that' too.

Guess it really depends on which teams/coaches are the sheep, and which are the sheperds.
