I honestly don't think Bron fakes that.
He seems like he genuinely enjoys building camaraderie with his teammates, he just has passive aggressive tendencies when he's displeased whereas a guy like MJ would directly get in your face at practice or during film sessions. All HoF, iconic level ballers are demanding in their own way and I much prefer the direct approach, but there's been too much love shared about Lebron from his teammates for me to believe he doesn't genuinely make an effort to form a relationship with his guys. Most issues with Bron don't stem with how he approaches the team when things are on the tracks, it's how he handles it when the train goes off the rails. Being nonconfrontationally passive aggressive doesn't make you phony, but it can be annoying.
