Yea, it should be banned from the field. Its not more of "having an edge" rather than "being able to get away with profanity, and poor sportsmanship."

I've seen some of our players get thrown out of a game (and the next 2 because it was a red card) because he cussed at one of his own teammates and ref overheard...And I've also seen the refs not even GLANCE at a guy that cussed AT the ref.
