FWIW, I have a friend that is close to a MAJOR donor. He said that KF is enjoying his job as much as ever. With the comfort level he has with his 3 coordinators and a great recruiting staff, there is less pressure on him from those aspects as ever.
I don't think he's been very involved with the defensive game plan for quite some time. Seeing the change in the offense, it's obvious that he was right when he said that Lester is in charge of the offense. Special teams is what it is. There's no question he still has input, but I'm sure he's got a pretty high level of confidence in those 3 areas. I'm sure that the stress of being the front man is the same as it's always been. People wanting him gone. PR events. Idiot media, managing all the things that come up with players, boosters, admin, etc.
