This is why it is hard to compare the two. Jordan would have the potential to avg 40 a night with the current rules. LeBron would be guarded totally different in Jordan's era. LeBron shares the basketball more, or is that because Jordan played in a era where sharing wasn't caring. I will say this, if you get a time machine, give them both their best teams that won titles, there is no way Jordan lets LeBron beat him. Jordan had a killer instinct like no one before or since. LeBron doesn't have that, which is probably a good thing for his likability, but not for his title chasing. That said, Jordan would have never left Chicago in his prime to play on someone else's team. Take a sabbatical yes, but he would never have left to go play with Charles Barkley in Phoenix.
I am not a LeBron fan, but he is certainly in the conversation of best ever. But for me, watching Jordan play basketball was better than watching LeBron play basketball. Maybe because I was 8-18 years old for Jordan's prime and I am older for LeBron so it isn't as magical.
