LeBron's defensive IQ is off the charts here. At 40 years old with the longest career in NBA history, he's mastered the art of energy conservation without sacrificing impact.⁣ ⁣ Watch how he switches off pin-downs and zones up on the block - this isn't lazy defense, it's brilliant positioning. He's disrupting offensive flow while barely moving, then saving his legs for the moments that matter most.⁣ ⁣ That steal and save in transition? Pure veteran savvy. He knows exactly when to turn it on and when to coast. This is how you play smart basketball and extend your prime well into your 40s.
