Magic was a beast dont get me wrong but his athleticism for being 6'9 in speed, agility, & explosiveness
was not on level of todays hybrids. Lbj is a great help defender but he is still a poor on ball 1 on 1 defender. HE gets more credit for his defense then he really should. Pippen is closer to MJ & Kobe mold then Lbj.
If MJ or Kobe where LBJ size with his same athletiicism there would be no question who the gr8test really is. LBJ mental approach is kind of oxymoron when u look at how he lables himself King james/chosen 1 & wants to be richest athlete = he wants that greatness & doesnt care of being viewed as elitist or snob. BUt he dont want the pressure of closing routinely cuz he doesnt want the selfish label tag on him. Its the enigma of his gr8ness.
LBJ to me is in the mold of MJ and Kobe just less aggressive and more passive. But he is good defensively, plays in the post, and can shoot from anywhere on the court probably slightly better than MJ could.
I think you may be underrating Magic a little though
