In basketball parlance, the step back is a move, not a method. If there is “research,” it is immediate—nothing protracted in the decision to make the move. I have never heard anyone refer to practiced, foreseeable basketball actions as methods. Instead: for individuals, moves, techniques, tendencies, styles; for teams, systems, plays, schemes. The step back introduces sufficient space for a shooter to send one up unobstructed (or with reduced interference from a defender who, because of the step, is now a step away). The step back creates a clearing.
For this step back to be effective, one judges by the space it established—usually a small, quickly opened space. Was it sufficient? And was it quickly enough calculated and executed to become indefensible? I want to be careful in suggesting that this step back compares neatly to the other step back. We do not on the hardwoods, say, in a pick-up game, wish to be running with anyone who noodles on, ish-talking about “did you see my step back method?” No. Time we shoot for new teams.
