Mike Shanahan jokes about the Raiders' coaching mess

Denver Broncos coach Mike Shanahan, who once coached the Raiders under Al Davis, yuks it up when asked to comment on the firing of Lane Kiffin.

"To be honest with you, I was a little disappointed. When you take a look at it, I was there 582 days. Lane Kiffin was there 616 days. So what it means is is that Al Davis liked Lane more than he liked me. And I really don't think it's fair. I won three more games. Yet he got 34 more days of work. That just doesn't seem right. Does it to you guys?"

Pretty funny stuff, for a football coach. What I want to know is who counted their number of work days with the Raiders. When Shanahan jokes, he obviously does his homework.
