Props for being stand-up about it.
To me (as many have said more eloquently - I believe what MJ had, that LBJ just doesn't, is that killer / closer / finisher instinct.
MJ's leadership style (which would be frowned upon in most environments) was to literally fight or beat his teammates, if they gave less than 100% when the titles were on the line. True killer instinct, and he forced others on his team to have it as well. Also, he NEVER shied away from taking the last shot(s) or locking down the best scorer on the opposing team. Put the pressure on him - he's fine with it
LBJ - AT TIMES - when it comes to crunch time, he is seen complaining about what call he didn't get.... or giving up on defensive efforts.... or passing off to somebody else. You can say that is unselfish, but its also not being "The Man" / "The GOAT" when it matters most. And to his teammates, when they see him constantly complaining or giving up on defense, or not hitting the boards, they have this look like: "oh OK so THIS is how WE ALL should roll now?!" Wrong/poor "leadership by example".
