Not necessarily, totally transformed the game of hockey when they removed the offside rule, made the game faster, more open and more exciting. Not saying it would work in football, but i think its an interesting option i have often wondered about. Make throw ins, kick ins, again that would make the game quicker and far more impact from a throw / kick in. Treat injuries on the pitch and let the game continue whilst being treated, pretty much like rugby i think. Would get rid pretty quick of all the fake injuries and make the game more fluid.
