It makes plenty of sense. Player-coaches are a real thing, and in a realm where you're not worried about peak fitness then it's reasonable to demand the coaches become player-coaches.
replyPlayer-coaches are a real thing, but noticeable because of how rare and unusual they are. The problem is that the analogy doesn't even hold up in the source its referring to.
replySure, there are good player-coaches, but there are also great pure leaders. There are also very bad player-coaches. A coach who is trying too hard and too deep to be a player when they are less "fit" (or skilled) has historically led to many problems in many cases
It's not a deep analogy. It's not saying player coaches are inherently better, but in their particular situation they want the managers to be coding.
replyThere's not much equivalent to "fit" here, just skill, and they decided they don't want the pure leaders, they want ones that are knuckle deep in the sausage.
Good decision or not, that very basic analogy is completely fine.
