Why do drilled techniques fail during rolling?

Drilled techniques often fail during live rolling because traditional drilling builds what researchers call context-free technique - mechanics without context. This can fall apart the second a situation changes. You might drill hundreds of armbar reps, but if your guard gets passed before you can set it up, the drill did not prepare you for that reality. CLA addresses this by embedding decision-making, timing, and unpredictability from the start.
