Don’t agree on Easter at all.
Always assume he was a major part of the problem - coaching his best mates with all the allegiances and history that brings and part of a coaching team who had all been there a decade
No sane business would do it.
Find myself both agreeing and disagreeing with this. All comes down to character of the individual involved so I feel it's by degrees.
You could say that NEv came through in just the same way. The question is whether they can command a different kind of respect from the senior players in the squad when they retire compared to the respect they had as part of that cohort as a player. What we may never know is how much Nick Easter's short stint as defence coach was primarily down to his failure to shift that relationship between himself and the likes of Joe, Mike, Danny, Chris - or other factors. Probably a mixture of both, ratio unknown.
The business analogy actually contradicts your argument - people get promoted into management from the main working pool in companies across the country every day. The success of that promotion often comes down (in part at least) to how that individual is able to transition their relationships with those who used to be their peers - and how much support they get from the suits above in order to make that transition successful. Of course, there are always multiple factors at play.
