If what is happening is as Fry is reporting, there is no way this does not get back to KF. It would already be in KF's knowledge. I mean, if some nobody like Fry is reporting this on a message board, you don't think that KF's agent or others in his orbit would not tell him about it? And whatever details Fry knows, I am confident KF knows more. This type of thing involves too many people and is already out. IF IT IS TRUE.
So how does this work? KF goes about his business, Beth strikes out going after this whale. Then what? "Kirk, we'd love for you to coach our team again next year." "Um, go F yourself."
This is not the way the real world works. If Beth and Fry's dark mystery boosters are actively pursuing a replacement for KF, then KF is already done for next year. He is not some 36 year old interim coach that finished off the season well and can be kept on the hook like this. He is a legend. There is no dipping your toe into the water for replacing a KF. You either pull the trigger like you did with Fran, or you bring him back.
If they are shopping for a new coach, KF knows that and has already been told he is done or has already told Beth he is done. So, if any part of Fry's rumor is true, KF is, in fact, done.
