Few interesting ideas, makes a change from the old suggestions like the players should wear shorter shorts.
Pen for denying a goalscoring opportunity sounds good, but in practice it will be used to give the likes of Man u a let off at the end of a game. Like the current offside rule I'm against any thing that is completely up to the referees interpretation.
Imo they should just have clear cut rules, with heavy fines to inconsistent referees.
