What Are METLEs?
METLEs: The Building Blocks of True Athletic Development
At the core of Sports University’s Triangular Training Theory™ (T3™) lies a powerful concept: METLEs, or Mission Essential Task List Executions. METLEs define the sport-related, position-specific tasks athletes must be able to execute in response to the endless variety of in-game stimuli. They are the atomic units of athletic performance—the individual actions that, when mastered and combined, separate elite players from everyone else.
What Are METLEs?
Every sport and position carries its own set of essential tasks. For a wide receiver, it may be breaking off a press release or tracking the ball over the shoulder. For a linebacker, it could be shedding a block, reading a key, or closing the gap on a ball carrier. These individual movements, reactions, and executions are METLEs—the foundation of an athlete’s ability to play their game at a high level.
But METLEs go beyond just knowing what to do. They are about the athlete’s ability to:
- Execute the task with precision.
- Repeat it with consistency.
- Adapt it under pressure and in real time.
From Tasks to Combined Functions (CFs)
As athletes develop, they begin to “stack” or combine METLEs into more advanced units called Combined Functions (CFs).
For example:
- A cornerback may combine a METLE of “jam and reroute” with the METLE of “turn and run in coverage.”
- A running back may stack “ball security on contact” with “breaking an arm tackle” and “accelerating through the hole.”
This stacking process is what allows athletes to progress from raw execution to fluid, adaptable performance. The more METLEs they master and the more CFs they can execute, the higher their Combat Rating™ becomes within the T3™ system.
METLEs Under Pressure: The True Separator
Training an athlete to perform a task in a controlled environment is one thing. Training them to perform that same task under the pressure of fatigue, physical contact, and unpredictable game conditions is another.
This is where METLEs prove their true value. Anyone can rehearse a skill in practice, but not everyone can reproduce it when the game speeds up, when bodies collide, when decisions must be made in a fraction of a second.
In T3™, an athlete’s ability to execute METLEs and Combined Functions under pressure is the ultimate measurement of development. It defines not just who can play the game, but who can excel at it.
The Role of METLEs in T3™
T3™—Triangular Training Theory™—defines three Aspects of Development (AODs):
- ATCs – Athletic Traits & Characteristics.
- METLEs – Mission Essential Task List Executions.
- MTR-F – Neuromuscular Training & Adaptation.
Together, these form the complete framework for understanding and advancing athletic ability.
Within this system, METLEs are the sport-specific layer. While ATCs measure raw athletic potential (strength, speed, power) and MTR-F builds the neuromuscular foundation for adaptation, METLEs are the bridge between potential and performance. They make an athlete’s development real and functional, turning athletic traits into actual game-day execution.
Why METLEs Matter
- They define what winning looks like at the micro level—down to each movement and task.
- They provide objective clarity on where an athlete stands and where they need to go.
- They allow trainers, coaches, and athletes to measure progress in tangible, game-relevant terms.
- They ensure development is position-specific and battle-tested, not just generic drills that look good on film.
Simply put: If you can’t measure the METLEs, you can’t measure the player.
Final Word
In today’s athletic landscape, it’s not enough to be fast, strong, or skilled in isolation. The difference between a good player and a great one lies in their ability to execute METLEs and stack them into Combined Functions under live, pressurized conditions.
That’s why within Sports University’s T3™ framework, METLEs are more than just a checklist—they are the true currency of performance. Master them, and you master the game.
