For whatever reason, men growing insane beards has been taken to a new level in recent years. Brett Keisel of the Pittsburgh Steelers has grown a crazy one and we have seen the entire 2013 Boston Red Sox squad grow beards as a sign of camaraderie. Even Bengals defensive tackle Domata Peko has a legendary mane. We also can't forget former San Francisco Giants and now Los Angeles Dodgers pitcher Brian Wilson's pirate-like beard.
