This isn't 1985 anymore. Bashing into the line of scrimmage and then running a waggle off play action doesn't work anymore. Coaches are more in tune with matchups of speed/space than they have been. They are willing to let you have that "3 yards in a cloud of dust" because they have come to realize that an offense cannot function that way. It isn't a race to 15 points anymore. It's a race to 40 or even more. Defense isn't about getting stops, it's about limiting damage. Consequently, offense is about cutting other teams apart. Bill Walsh was thought to be an offensive innovator. He isn't half the offensive football mind of Leach, Kelly, Meyer, Rodriguez and all of these guys who have designed offenses that not only out-execute you but make at least one defender wrong on a regular basis in the run game. Football is so much more complex than it used to be. You can use KSU. They run that run/pass option play and it has now developed throughout the season. Teams run packaged plays. Teams can literally do 4 different things out of one play call. The teams that aren't complex are teams that, physcially, are better. Alabama has better players than you no matter who you are. They run a vanilla offense because their line can handle yours on both sides and they are bigger than you on both sides all while being faster.
