-- Because they can shift to those "heavier" concepts out of 11 personnel, they can still be under center almost every first and second down: "Now you've got the full gamut of your run-pass stuff. Kansas City does a phenomenal job of running the ball in the gun. But just based on the nature of the position of the back, you are limited with the inventory of runs that you can give to a defense, just based on getting it from an offset gun as opposed to the home position. And everything we do is predicated on our players. There's a philosophy and there's a fundamental system. But this thing has taken on an identity of its own as a result of how smart our players are. We've got good players that we want to try to keep pressing the ways of getting them involved in a variety of ways ... but if you have a quarterback that you can ask him to win the game by throwing it and receivers that can separate and then you have a back who is as special as Todd, it makes it tough, if you have the ability to legitimately run and throw the football, and if you can have [defenses] say you've got to take one or the other way."
