This reeks of "back in my day" nonsense.
LeBron has statistically been the best clutch player for going on a decade and the ultimate proof is coming back from 3-1 against a 73-9 team in the Finals.
As great as Jordan was, his team was always favored in the Finals. When he retired, his team still went to the ECFs without him while LeBron's teams fell off the face of the Earth without him carrying them to the Finals every year.
As has been said, there's an argument there, but those who think Jordan is clearly better are... to put it nicely... completely clueless.
