It's sad to see the ignorance in the people on-line where there are good sources of info if they bother to look around for them.Things like this I'm still confused how players that are not beginners don't know what the rule is. Along with what a push shot is or a double-hit foul at close distances. Or if the ball is on the "line" with the base or edge. Those are all clear rules if you don't count league modifications or "I have seem Billy Joe Bob do this in a tournament in 75 and the ref let him". There was a shot Eckert posted a year ago that was a clear push shot and half the people in the comments were saying it was legal, someone just posted this week that it was legal to a reply of mine a year ago. Just silly.
But the saddest are the tournament players who have no idea what the real rules are. They have never bothered to read them and you don't have to know them to become a "professional" player.
