I saw a D1 wing on a tv game wearing shades this past Saturday afternoon, don't remember which game. It isn't usual by any means.
As to the other elements, and this may have to do with the declining number of officials, I've had guys in my group sporting beards like Grizzly Adams since the Duck Dynasty craze, I'm seeing tattoos not covered anymore, and a new kid this year is still sporting his ponytail since he joined this summer. Since I came up when all that was considered a no-no, I'm conflicted. I really don't like it but I've heard none of the guys older than me saying anything about it so I've kept my peace.
