Spot Throw-in

[BillyMac]

A player inbounding the ball may move backward as far as the five-second time limit or space allows. In gymnasiums with limited space outside the sidelines and endlines, a defensive player may be asked to step back no more than three feet.

Players should know this rule without us telling them. The most I'll do to help a player on an endline throwin is to say, "You have the whole line", while pointing down and swinging my arm back and forth parallel to the endline, or, "This is your designated spot", while pointing to the designated spot.

You should have told the player he can move back if he wanted. Along with he only has 5 seconds to throw it in, he can't step inbounds before releasing it, he cannot change throwers on a designated spot throwin but can after a made basket, also inform him of the backcourt exception... blahblabalbalbablabllalh.
