It may include allowing for two steps, not one as currently written
What? There has always been two steps. The crab dribble is part of the two steps, isn't it basically a jump stop/pro hop/hop step?
b. A player who receives the ball while he is progressing(moving) 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.
So, they do allow three steps if both feet touch the floor at the same time after receiving a pass, which means you can take one more step or pivot.
