I guess I don't understand how any one can sue.
I mean when the NCAA made a new rule that forbade dunking, Lew Alcindor couldn't sue. He was playing their game, he could play by their rules.
When the NHL cracked down on hooking after the strike, Sergei Gonchar should've sued, that was the only way he could play defense.
IndyCar mandates all tires be made by Firestone. That's a rule to play the game. USGA makes rules, PGA Tour says 'these are the rules we play by', Tour players can choose to play by the rules or not play.
Meanwhile for my games at the club, i can use a non-reg putter just like some guys play by winter rules in June.
That said, the ball seems to be a FAR bigger problem than long putters....
