Why "Repetition Without Repetition" is the Key to Basketball Skill Transfer

Two ideas from the constraints-led approach (CLA) close the gap between practice and games: repetition without repetition and functional variability.

There is nothing more frustrating than watching a player who looks like an All-Star caliber player in a 1-on-0 workout but turns into a turnover machine the moment the game starts.

Think of the point guard who has "perfect" passing form in a line drill but throws the ball into the third row when a defender's hand enters the lane.

As coaches, our instinct is to say, "They just need more reps." So we go back to the gym and run the same drill 100 more times. But the exact same rep, over and over, may leave them less prepared for the game, not more.

See this wrap around pass by Harden. How can we design small-sided games (SSGs) where players can work on these types of passes (or similar passes)?

What is "Repetition Without Repetition"?

The term comes from Nikolai Bernstein, a neuroscientist who studied movement nearly a century ago. He observed expert blacksmiths hitting an anvil with a hammer. Even though the result (the strike) was consistent, the path of the blacksmith's arm and the angle of the hammer were slightly different every single time.

In basketball, we often mistake "repetitiveness" for "repetition."

• Repetitiveness: Doing the exact same movement pattern over and over (e.g., a form shooting drill with no rim.)
• Repetition Without Repetition: Repeating the process of finding the outcome or the solution while the movement itself varies to meet the demands of the environment.

Think about an outlet pass. In a game, you never throw the exact same outlet pass twice. The distance changes, the speed of your teammate changes, and rebound location changes. If you’ve only practiced a "textbook" chest pass in a static line, you haven't learned how to pass; you've only learned how to perform a choreographed move.

Why there is no "perfect" form

We are often taught to coach "optimal" movement patterns. We want every jumper to look like Ray Allen and every layup to have the same footwork. But the game doesn't care about "perfect" form; it cares about functional solutions.

Functional Variability is the ability of a player to adjust their movement to achieve a goal. If a player is driving to the rim and a defender is in the way, they shouldn't be trying to use "perfect" one, two step footwork. They need the variability to finish off the "wrong" foot, use a high-off-the-glass scoop, or an extended finish. See example below.

If you coach the variability out of your players by demanding they do everything "your way," they have one solution. When the defense takes away their "one way" of doing things, they have no Plan B. (not to mention they may be constrained so they can't find a better way to solve the problem. Read the Bill Russell x 'Red' Aurbach example here.)

Coach's perspective: Skill is solving problems. Design practice so players face problems to solve instead of answers to memorize.

Small-sided games build adaptability

The best tool for building functional variability is the use of Small-Sided Games (SSGs). By manipulating the number of players, the space, or the scoring rules, you push players to find new solutions.

Simply adding a defender into drills will create a decision and force repetition without repetition.

Why messy practice helps

One of the biggest hurdles for coaches is that Repetition Without Repetition looks "messy." There will be more turnovers. Players will look confused. It won't have the clean, aesthetic flow of a scripted drill.

Learning and performance are not the same thing. If a practice looks "perfect," your players are likely just performing a task they already know. If they are struggling, fumbling and trying to find new ways to score, they are more likely learning.

Especially for youth players (Under-12), the coach's job is often to stay out of the way. "Let them play."

Your next practice

Start with these three steps:

• Remove the Lines: If there are more than two people standing still in a drill, change it. Add a defender or make it a game.
• Add a Constraint: Instead of telling them what to do, give them a rule. "You can't use more than two dribbles" or "You get double points for a corner three." This forces them to find variable solutions.
• Let them play: Don't blow the whistle every time something goes wrong. Let players play through the mess so they learn to self-correct.
