At the risk of taking heat ...

It could be that different areas of the country have different definitions for the jump stop.

In my area, the NFHS definition of the Jump Stop is jumping off one foot and landing on two. That is the only context around which I have received training concerning the jump stop. I accept and understand that other areas of the country refer to the jump stop as landing on two feet.

Coach P is correct - the NFHS rule book does not define what a jump stop is specifically. And BZ, since when to we use Google to define basketball terms? We usually defer to the rule book and if it is not specifically defined therein, we accept that. The NCAA may have defined the jump stop specifically, but again, rules and simple nuances have been known to differ between the NCAA and the NFHS.

What is important is to refer to the current rule set for the game to know what is allowed and what is not allowed after getting possession of the ball.
