MtheGM - I do not believe that the game is in any way - both for the players and spectators - detrimentally affected by the present off-side rule. As a great believer in the "If it ain't broke don't fix it" philosophy I say leave well alone.
As an ex-cricketer I think you both may have a point with LBW. As an opening batsmanI have had many an afternoon spoiled by a white-coated official who didn't understand the rule properly. My son who followed in my footsteps has been known to throw his bat through the pavillion window when having been given out LBW when he wasn't....lol true !!!
Having said that it is a very difficult set of rules to understand and even with the help of Hawkeye etc they still get it wrong.
So though I would be an advocate of changing the rule I haven't a clue what I would do to improve it, unless you did away with it altogether.???
