I've expressed similar views. Developing coaches should be as much a priority for clubs as developing players.
Perhaps a rule requiring coaches to sit out for 96 weeks if they want to transfer to another club might address the issue?
It might, or alternatively, it might stifle someone who has the potential to make it as a top coach but just isn't getting a chance at his own club. He either has to grin and bear it, or else be out of the game for two years
I think clubs are their own worst enemy here.....They bring in an external coach, paying them large sums of money, but very rarely is there any knowledge transfer from the paid coach to the club coaches.....
