NFL referee's have gone to a new look. I can take or leave their new sweaters, but I really don't like the pants they have been using on a trial basis in some games.
The pants are basically black with a white stripe up the sides. I Found them harder to pick out from the players. Maybe that's the idea to help them blend in? Personally I think they look to casual.
I think the uniform the CFL referee's are using look more professional.
