I pack an electric razor in my bag and shave before every single game. I hate the feeling of working a game with a seven o'clock shadow.
I believe that the original poster was not only asking about facial hair (beard, mustache, etc.) or whether, or not, the official shaved that day (five o'clock shadow), I believe that he was also asking about the modern style, as worn by sport's, Hollywood's, and music's, most famous: the straggly unshaven almost beard "look". My son wears this look, going unshaven for a few days, not because he's lazy, but because he's going for that "look". I hate it when I give him a kiss goodbye on his cheek, it's not a good feeling. I don't know how his wife stands it?
Here's the "look" as worn by Justin Timberlake:
