So interesting that we read "staff changeS" immediately as Jon. And that's the big problem with any kind of nepotism - it's an immediate grievance magnet, whether warrented or not. It was long ago decided with zero evidence on this board that if there was a problem w assistants, it must be Jon.
To me, it makes more sense that it was Sam, since we've also already heard that recruiting was the main problem. Seems like the AD would have already known Jon and Kellie were a package deal and never offered that as an option. Also could be more than one change the AD was after.
Whatever, KJH did the right and noble thing by refusing. Shuffling deck chairs again after two years would not have been it.
