A good science experiment eliminates every variable but one; time, weight, volume, habitat, or maybe person.
It looks like the Kansas City Chiefs passed their lab science credit in college. By hiring Romeo Crennel as defensive coordinator, they have essentially eliminated the last personnel variable in their apparent experiment of the value of a head coach.
Romeo Crennel coaching defense, Charlie Weis coaching offense, Scott Pioli running the show, Mike Vrabel leading the defense, and Matt Cassel either on the bench or on the field.
Sound familiar anyone?
It's a true test of just how important a head coach is to an organization.
The Patriots haven't won a Super Bowl since the absence of these three men.
These three men haven't had success without Bill Belichick.
Kansas City just hasn't had success (at least not recently).
So the Chiefs have decided to bring everyone back together besides the head coach and hope that the Patriots' success was more about the entire staff and less about the supposed genius that led the team.
Now, obviously the Chiefs don't have all the same players, and no, Matt Cassell isn't Tom Brady, but the trademark of the Super Bowl Patriots team was turning everyone and his mother into a top notch NFL talent.
Troy Brown became a great cornerback, Mike Vrabel became a red zone threat, David Givens and Deion Branch were feared wide receivers, and even Tom Brady went from nobody to household name.
That staff's ability to mold average players into stars is undeniable. What every football mind should wonder is, "Who is responsible?"
Well wonder no more, because the Kansas City Chiefs will answer all your questions in the next few years.
If the Chiefs start winning and guys like Brandon Flowers, Lance Long, Dantrell Savage, and Andy Studebaker start heading to Pro Bowls, then consider Belichick a figure head, stop worrying about a big name coach, and start giving assistant coaches some hefty contracts.
If the Chiefs still stink, give Belichick his Canton bust and continue to not care who positional coaches are.
Chances are that both sides are partially responsible and, therefore, both the Chiefs' staff and father Patriot will continue to miss one another and wonder what they can do to replace the missing pieces.
But pay attention.
The Chiefs have given sports fans everywhere a rare opportunity.
A chance for a clear-cut answer and a chance to understand what truly makes the best dynasties just that.
