Yeah, I gave up on pushing that months ago. The market would sort them out but, for whatever reason, it's not been enacted.
With players retiring and asking for coaching jobs, there's really no concern of the owners hiring all the old guys(which we will) and then having a coach shortage when they retire. It's a fluid market. The biggest problem I can see is the possibility of lesser coaches at some point. Of course we'd hire the best, and they'd be older, who'll eventually retire. Then, at some point, I imagine we'd see 33 coaches with 75 ratings instead of the the current 85 we see with 75 ratings. Then we'd have the ol' "WE NEED MO' BETTER COACHES!!!!!" like we've seen with FI since the beginning of time.
