whistles&stripes - you've posed a good question about continuous motion! at the HS and NCAA levels, WAY TOO many made baskets are cancelled by officials who do not understand continuous motion.
believe it or not, the continuous motion definition is the same in the NBA as it is in HS and NCAA.....(just tell that to the coach that complains about you scoring the basket for the other team when his defender commits a foul....."hey ref - this isn't the NBA!"...."coach, of course not - but the rule is the same!...
