What you and everyone else WHINING about a defensive change needs to realize is one thing:
We have built nothing on defense.
We do not have a good defense.
We have a few good players who have experienced a modicum of success over the course of 2-3 years.
Changing it is NOT the end of the world.
Better to be the bastard child of a king and his whore than to be a ****ing peasant at the shite homer trough.
