I have no connection to Kiffin. I don't care what or how he does out in California. But, it doesn't take a genius to understand that he's in an impossible situation out there. That isn't my opinion. It's the truth of the matter. I don't feel sorry for Kiffin. He's the one that wanted to go out there (albeit before the sanctions hit).
The fact that you don't understand how energy and willpower affect defense in particular speaks volumes for your knowledge of football. Their offense has been fine aside from the last 2 weeks when Barkley went out. You take the will out of a football team, and the first thing to go will be the defense. Voila... that's where they blow this year. They have zilch to play for, and it's glaring on that side of the ball.
And, Al Davis is a complete moron. If he had left Kiffin alone, they would've been fine under him as the HC. Davis is like a lot of owners... they think they know the sport of the team that they own b/c they have a lot of money or just lucked into owning the team. Prime example: Davis wanted Russell, Kiffin didn't.
