Throughout his career in the NBA, Los Angeles Lakers forward LeBron James has been a dominant force on both ends of the floor. Although he may not be the lockdown defender of old at 35, he’s had some iconic moments defensively during his Hall-of-Fame-caliber career that put him in elite company like his unforgettable chase-down block in the NBA Finals against the Golden State Warriors.

On Tuesday, the Lakers superstar opened up about the origin of his defensive mindset and the one coach that challenged him to improve on that end of the floor while with the Cleveland Cavaliers.

“I’d probably give a lot of credit to Mike Brown,” LeBron said. “He came in with a defensive mindset with a defensive strategy to Cleveland when he got the head coaching job. He told me he wanted me to be just as good as I was on the offensive end; he wanted me to be even better on the defensive end, and it started with a lot of communication.

“I wanted to take that next step in my career because I wanted to get better, and I wanted to compete for championships. I started to take that leadership as far as my communication being loud, speaking calls out, getting into the film session a little bit more—diving into that.
