Bird (Similar level of player but LeBron will have absolutely destroyed him longevity-wise, also more MVPs, finals MVPs, All-NBA, All-Defense)
Kobe (This one is barely worth mentioning. LeBron has more MVPs, Finals MVPs, not in the same league as LeBron as a player. LeBron's career FG% >>>> Kobe's best season from the field)
Olajuwon (LeBron more MVPs, All-NBA First teams and will have more overall, more rings, Olajuwon's '87-'93 period of languishing on mostly 40-odd win teams and getting bounced in the first round)
Wilt (LeBron, more championships, more Finals MVPs, same amount of MVPs in a far more competitive era, more All-NBA, All-Defense, inflated era stats)
And he has a very strong argument against Duncan, Shaq, Russell and Magic but I can't be bothered writing any more as it's absolutely ludicrous that someone would argue he's not top 10.
