I see this one as Fox's selection. It looks like he wanted to get rid of lambo, had Sherwood waiting in the wings but needed to get permission from Randy. After Hull, was given permission and made the switch.
If at all true, it means the next few months will not only tell us about our manager and league future, but likely also whether our CEO is up to the job. Lerner clearly isn't capable (or interested) anymore, so our best hope other than being sold is that Fox is capable of running the club.
