A number of athletes have been growing long beards. As a result, many look like they live in a log cabin, one where all of the tools have some sort of blood stain on them. It is a look that was really only fashionable in 1970s horror films. You can put the guy in a sport jacket with a nice collared shirt, but he is still going to look like the reason those campers were never heard from again.
These are not nicely groomed beards. These are beards that suggest you might be plotting an act of domestic terrorism. I suppose the beards help to intimidate the other players . . . and anyone else not carrying a gun. Still, there must be a way to seem imposing on the court or the field, while off the court not looking like you just came from a police lineup.
