So having your team full of clean shaved faces shows a team that is selflessness. There's no way for a team to stand up, united, because of an outdated philosophy?
You're telling me that this team will be better united because it does the little things together, like shaving and having shorter/well groomed hair?
Even the Army, of any nation, doesn't care if you grow a moustache. Bears are now wildly accepted for many reasons. The used to be restricted because a beard would obviously amper the use of a very important Gas Mask...That's it.
But whatever. I get the symbolism, but it's still won't do much.
First, it's an initial step. An initial step toward reforming the culture that has instituted failure as though it was success. No one is saying, send a squad of clean-shaven ECHL players against bearded NHL champions and <poof> The Toronto Maple Leafs will win the Cup. It is a process of developing team uniformity. They can complain together. And they can grumble together about how even militaries under some flags aren't required to shave, etc, etc...But even that is a step towards a single minded purpose which is being sent from the top and enforced by the top.
The club may have yielded a better haul from other clubs or Pittsburgh itself for Kessel had it waited longer, but timing is vital and sending a message is a boon for a directionless club by management who know that the team comes before any single individual. There was obviously a clear mandate to establish leadership in every way shape and form. That in as much as acquiring a first round pick and KK advised the speed of the move. And it advised bringing in Mike Babcock and Lou Lamerillo for goodness sake, lol.
And your comparison of militaries not having grooming standards is a complete fabrication. They exist in so far as the circumstance demands. You're not saying successful militaries operate without standards, right? Maybe Hafthor and Jan-Rune of the National Faroe Islands Armed Guard can grown berserker beards and wear icelandic sweaters to war, but I doubt the personnel in the Russian submarine rising to meet them do.
"But whatever. I get the symbolism, but it's still won't do much."
Apparently men whose profession is hockey and who have won championships beg to differ with your characterization given that they've instituted it as a professional policy.
