93 MJ is peak MJ. If you put peak LeBron on this team they aren't down 3-1 either so that argument is pointless. You're basically talking about LeBron with the milage of Wizards Jordan, this is todays LeBron! The fact that he's still playing at this level is incredible.
Around 4-5 years at this level should get it done. I mean, I already have LeBron top 3 all-time, he might even be second behind Jordan. I have their peaks at about the same level and while I do think that Jordan had a couple of more better seasons than LeBron, LeBron will have a chance to make up for that by beating him (handidly) in longevity. If LeBron keeps this up for another 4-5 years, it's going to be hard to argue for Jordan whose longevity was cut short by both injuries and the fact that he stopped playing for 1.5 years in his prime. That matters.
Let's say LeBron keeps this up for another 4-5 years.. He'll have a total of 17-18 seasons of great play (im excluding his rookie year). Jordan had what, 12 years? 13 years at most at this level of play. Sorry but I rather take LeBron for his career at that point. Their peaks are about the same and Jordan being a little bit better for a couple of years won't make up for LeBron having 5 more dominant seasons. Having LeBrons career gives me a better shot at winning in this scenario basically.
