Over the past few weeks we’ve been rolling out replays from the SoCal Coaching Summit on SGTV. This week features Drew Dunlop of The Pro Lane, who opened the event with an insightful session on his player development system built around game-like scenarios, tempo, and decision-making.
Coach Dunlop is no stranger to Slappin’ Glass, having collaborated with us on the “Modern Game Truths“{🔒} series. Together, we’ve explored practical training methods that connect the controlled practice environment with the dynamic game setting. Emphasizing the skills, movements, and decisions that appear most often in games and methods to tie skills and systems together.
At the Summit, he presented on Ecological Design in Player Development, moving beyond theory to deliver practical applications and live demonstrations. His session highlighted how coaches can shape training environments to improve decision-making, design effective warm-ups (“Ready Ups”), and advance both player and concept development.
What is “Ecological Design?”
Ecological design centers on creating environments where players discover concepts by solving realistic problems rather than rehearsing scripted solutions. With this approach, Coach Dunlop structures his player development sessions in ways that look very different from a traditional workout. Instead of heavily scripted drills where players repeat the same motions rep after rep, he uses dynamic game scenarios that challenge players to read defenses and make the right play.
Throughout his session, you’ll see a wide variety of drills executed at a quick, efficient pace and they are all directed towards a few core principles.
Principles That Fit
Everything Coach Dunlop does is rooted in Ecological Design, and while the specific drills and scenarios may vary, they always return to the same core principles:
1. Present Problems
Development begins with game problems. By exposing players to the real challenges they’ll face in competition, solutions emerge naturally. Many drills fail because they don’t replicate the true problems of basketball. Identifying and recreating these problems is the starting point.
Zooming In: Add a simple bad spacing start to the “2v1 Good to Great” shooting drill to better mimic the challenges of a real game, forcing players to relocate and find proper spacing against a closing defender.
2. Count Decisions, Not Reps
What matters is the quality of the decision-making inside each rep. Finding ways to create environments where players face multiple choices at game speed, rather than predictable, mechanical tasks. It’s about building smarter players, not just more practiced ones.
3. Violate Expectations And Break Rhythm
Adaptability comes from unpredictability. If a player can switch off mentally during a drill, the task isn’t serving them. Disrupt rhythm by inserting challenges (like tough passes, changing coverages, or unexpected scenarios) that force players to stay alert and adjust on the fly.
Zooming In: In “1v1 Hand-to-Hand Finishing,” players are immediately confronted with unpredictability. They must first create separation from an initial defender, then pursue the ball and finish against a rotating rim protector. The shifting nature of each rep, changing angles, contact points, and timing, ensures no two possessions feel the same.
4. Self-Scaling
Great design meets players where they are. Instead of isolating skill levels or ages, Dunlop creates shared environments where the same game scenarios challenge everyone. Each player adapts with the tools they have, ensuring the task scales naturally while keeping the training game-real.
Design Tools
Now that you’ve seen the principles that Coach Dunlop uses to create his player development sessions, let’s look at a few of his functional design tools:
1. Catalyst Constraints
Drawing from both Ecological Design and the Constraint-Led Approach, coaches can manipulate the rules of a drill to shift player focus and disrupt comfort zones. Whether it’s altering space, touches, or defensive coverages, these constraints force players to adapt and grow new skills in real time.
2. Variable Shot Clock
Every drill is tied to game context, and time pressure is central to that. By constantly changing the shot clock, coaches can introduce different layers of urgency, pushing players to make quicker, sharper reads under stress.
3. Reward The Precursor
In an imperfect game like basketball where not every shot is going to fall even if a player or team does the right thing, it’s important to find ways to value and reward the process and not just the outcome.
4. Scoring Systems
Competition drives engagement. By giving “points” for actions like extra passes or assisted paint touches, coaches can elevate the value of team-oriented decisions while ramping up the competitiveness of every drill.
What It Produces
At first glance, Ecological Design may seem more focused on the journey than the destination, but make no mistake — it’s about helping players improve efficiently, with benefits that reach far beyond traditional methods.
Players don’t just learn pre-set concepts; they create their own through affordances , the real opportunities the game presents in live play that blocked drills rarely capture. Rather than chasing one “correct” outcome, they explore different solutions, giving them multiple ways to win and more tools to succeed in varied situations.
Because training mirrors the unpredictability of the game, players develop built-in adaptability. The environment may feel more chaotic than traditional drills, but that chaos reflects real basketball, making the lessons more transferable to competition.
Zooming In: In Coach Dunlop’s “3v3 Power Play” drill, the offense is given three consecutive possessions. If they score on the first, they earn a man advantage on the second; if they miss, they play a man down before returning to even numbers on the third. Players are challenged to adapt their decision-making, spacing, and tempo on the fly, building the kind of flexibility and awareness that translates seamlessly to live competition.
And it’s not just about the players. Ecological Design also transforms the coach’s role. Instead of teaching plays step by step, coaches design problems that reveal concepts. This shift challenges coaches to adapt in the same way players do — sharpening communication, creativity, and responsiveness.
The result is a development model that accelerates growth for both players and coaches by bringing practice closer to the real game.
Bottom Line
Ecological Design makes player and concept development decision-centered, adaptable, and game-real. Instead of being taught in isolation, concepts are discovered through carefully designed constraints, pressure, and chaos that reflect the reality of competition.
