Don't know the point you're making....but it fails whatever it is
some rules have changed, but the foundation of the game, as in evolving, not really. I dont think its the game thats the reason Kiffen had a bad year. Its easy to blame one thing, and for you that may be ok, but id rather take a harder look at all the evidence. I feel its going to be some players, that fans had thought were good and just arent. I think forcing this scheme on the players didnt help and i feel certain coaches werent a help. Injuries werent helpful either. But the evolution of the game? Hardly. You still have to either pass or run the ball, so that hasnt changed. On defense you still have to stop the guy with the ball, so that hasnt changed. I dont care if you play a 3-4, a 4-3, a hybrid, or 11 guys on defense, you still have to tackle the guy will the ball. So clearly that hasnt changed, a few rules ON how to hit the guy, dont hurt an expensive qb, (thats opinion), but you still tackle the guy with the ball. Clearly Kiffen can instruct anyone to do that. Easily he can get his guys to tackle the guy with the ball, but formation, understanding job assignment, gap assignment, position, I am still not a fan of a CB being 10 yards off the WR, call me silly. But as for the evolution of the game, i dont feel thats the case.
