There's a surprising amount of beards in the UFC lately. I'm really not into facial hair, but I guess it does work to make some guys more memorable/recognizable. The worst for me is the pseudo-beard that guys like Griggs have (sorry, not sure if there is a specific name for this style). It's just weird.
I guess if a guy has to have the beard going, I prefer the trimmed/neat/short variety over the full on moses/amish thing. The shorter beards look more badass to me.
I wonder if Dave Herman kept his hairy mystique going after the last fight. It was hilarious and definitely a fun look, but I'm hoping he's shaved and smooth by the time his next fight rolls around.
