"N-word penalty". This seems like a PR nightmare in waiting for the nfl. The rule itself makes the league look good, but imagine the media shitstorm surrounding the first team to be penalized. I can't believe the players association isn't throwing a fit.
Obviously, it's wrong for players to say that on the field. But the offending team is going to make the player go through "counseling" or suspend him just to save face. It should have just been added to unsportsmanlike conduct.
