Section XIV-Traveling
a. A player who receives the ball while standing still may pivot, using either foot as the pivot foot.
b. A player who receives the ball while he is progressing or upon completion of a dribble, may use a two-count rhythm in coming to a stop, passing or shooting the ball.
The first count occurs:
(1) As he receives the ball, if either foot is touching the floor at the time he receives it.
(2) As the foot touches the floor, or as both feet touch the floor simultane- ously after he receives the ball, if both feet are off the floor when he receives it.
The second occurs:
(1) After the count of one when either foot touches the floor, or both feet touch the floor simultaneously.
c. A player who comes to a stop on the count of one may pivot, using either foot as the pivot foot.
d. A player who comes to a stop on the count of two, with one foot in advance of the other, may pivot using only the rear foot as the pivot foot.
e. A player who comes to a stop on the count of two, with neither foot in advance of the other, may use either foot as the pivot foot.
f. In starting a dribble after (1) receiving the ball while standing still, or (2) coming to a legal stop, the ball must be out of the player's hand before the pivot foot is raised off the floor.
g. If a player, with the ball in his possession, raises his pivot foot off the floor, he must pass or shoot before his pivot foot returns to the floor. If he drops the ball while in the air, he may not be the first to touch the ball.
h. A player who falls to the floor while holding the ball, or while coming to a stop, may not gain an advantage by sliding.
i. A player who attempts a field goal may not be the first to touch the ball if it fails to touch the backboard, basket ring or another player.
PENALTY: Loss of ball. The ball is awarded to the opposing team at the sideline, nearest spot of the violation but no nearer the baseline than the foul line extended.

보시면 "two - step"이 아니라 "two-count rhythm"이라는 말을 쓰는데요

아 이걸 어떻게 설명해야하지

그러니까 공 잡은 스텝 이후부터 카운트를 세는거에요.

그러니까 르브론이 레이업하기위해 첫 스텝을 밟은 시점은 리듬 카운트를 하지 않습니다.

그후 두 스텝을 카운트 하는거고

리듬 카운트를 다 썼으니까 세번 스텝밟은 이후에는 공을 보내야하는거구요.
