I'm with Lou when it comes to "draconian" grooming standards. These guys are paid a lot of money to travel around to play hockey. They can at least wear a suit and look professional(grooming standards). If I'm at the helm of a team, people will know that they represent something when they are going out. It's something that should be instilled.
If a guy plays his ass off every night, and conducts himself appropriately, I could give a damn how long his hair is. They're athletes, not bankers.
