If a player steps
on the line, they are Out of bounds, in the lane and shot a 2 point try if feet or other parts of the body touches it. I was not talking about on a throw in. If you would call a player touching the line that was unintentional in those examples a violation, you would call that a violation. In this case, a violation should be called for something that is accidental or intentional. And yes if you are at many courts, if you touch the line you will be on the court.
