I voted no. If you're dumb enough to wear your hair long, then I think it is a bonus for opponents. Just another thing to grab to knock you down without fear of a penalty. There was a speedy WR yesterday (can't think of name or team, sorry - maybe because his hair was covering his name, LOL) on the highlights that they showed getting dragged down by his dreads. If I was his coach his hair would be coming off today.
