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.
The Chiefs will finish 5-11, Alex Smith will play horribly, and Geno and I will cackle with glee while he burns Kansas City.
