I thought it would be fun to change or tweak some of the rules in the 3 major sports, I'll start with the NBA. First is goaltending by definition: "a player should not touch the ball or basket ring when the ball is using the basket ring as its lower base". In other words; when the ball is over the rim. The ball also has to have a chance to score, in officials judgment. As long as the player doesn't put his hand up thru the net then everything else is fair game. The officicals can't always see if the ball had a chance to score. After all it is the defenses job to "tend the goal".
In 2001 new changes were made, for instance the ILLEGAL DEFENSE guideline were eliminated in their entirety, but a new defensive 3 sec rule will prohit a defensive player from remaining in the lane for more than 3 sec without closely guarding an offensive player. Do away with it for the defense only. It really doesn't give them a great advantage. If a team want to put some big guy in the lane, that means the guy he's guarding is open for an uncontested shot. If they get burned enough, they won't do it anymore. Also there was no definition of what "closey guarded" means, within 2 feet, or 3 feet, or 4 feet.
My favorite for change is; When a defensive player goes up to make a block and the offense player moves into him so when he comes down (darn the gravity) the contact is made. I believe the offensive player initiates the contact and should be called for offense foul.
Just for GPs change the 24 sec clock to 20 sec.
