I think Lebron is the second greatest and MJ the greatest of all time. Has nothing to do with personal bias, simply what I've seen with my own eyes.
Well, for me, in the top 3, I will put Lebron in the last, just what I see also.
Here's how I rank them.
1- Michael Jordan
2-Kobe Bryant
3-Lebron James
Even MJ have spoken. lol
Michael Jordan Believes Only Kobe Bryant Is on His Level
