Defense always catches the offense. Always. No matter what adjustments you make, no matter how initially you sway it, the defense catches offense. It's an evolving thing. . . . I'm not concerned about a long-term advantage. You know we want to move the ball and why we obviously keep changing rules to help the offense. The reason you have to keep doing that is because those defenses keep tightening down. The guys are faster and bigger, and we've got the same width and length of a football field. There's no more room to run, and so you've got to give it a little bit of help.
