In the never-ending media discussion, MJ vs LJ debate is more present as LeBron's career is entering its final phase.
Everyone has their own opinion.
I still rank MJ above all. I saw his domination over opponents; both physical and mental, and then he repeated it until he got bored. Twice.
In my memories, he destroyed some guys thoroughly, like destroyed and then some. Drexler, Barkley, Ewing, Malone/Stockton, but in truth the whole league.
Along the same lines, I could easily imagine the two meeting in a playoff round, and then MJ maniacally competitive as he is, eats LBJs liver. Hannibal Lecter, Kayser Soze style. And in the end, LeBron ends up being remembered as the one who challenged Mike and failed miserably as all the others.
