In the NBA, or any sport for that matter, you have your trash-talkers, and you have your quieter types. More prone to verbalize their thoughts and feelings are Q1s, though Q3s (particularly the dominant Animate, sometimes-insecure #3 FEALs) can be talkers as well (as can insecure Q2s).
Draymond Green recently had a funny story to share of Brain Types (and character types) in action. A spunky #1 FEAR himself, he recalled when he tried trash-talking with Tim Duncan when he was just a rookie in the league. “My rookie year I kind of talked junk to everybody. In the middle of the game I started talking to Tim, and I had already got into it with somebody on their team. I don’t remember who it was. But I started talking to Tim and he kind of just stared at me. I just kept talking junk to him and he kept staring at me. At that point I realized during the rest of my career that I might as well not talk to him. Either, one, he is not going to talk back because he has no respect for me. Or, two, he is not going to talk back because that is who he is. Or, three, both. I figured then that was the last time I would talk junk to Tim. And that was the last time.
