In they're prime, MJ had the killer instinct. Lebron is stronger and can post MJ up. And would knock MJ on his ass if he tried his high flying shit. Speed wise, advantage MJ, Strength advantage LBJ.
Overall I give a slight advantage to MJ. Why?: Once MJ smelled blood, it was fuckin over. He would bury you and do so in a fashion that would break your will.
Understand I grew up on Price, Daugherty and Nance..........games called on the radio by the immortal Joe Tait. I fuckin hated MJ. But I respected his greatness. Lebron is awesome, and one of the all time greats. But 1-VS-1 -----MJ Wins 7 outa 10.
