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
If you do try to look the date on when MJ do say about such thing then its just right to say that LBJ isnt really that taking some spot that time.
