For mere there are many GOAT in NBA in different ERA, unless Jordan vs LBJ vs KOBE play ball at the same time on their primes.
There can’t be more than one GOAT, the term itself means “greatest of all time.” Right now I believe the GOAT in the NBA is Michael Jordan. If another one comes in the future, that means Jordan is replaced, not that there’s suddenly two GOATs.
Yeah basing from the title itself, though there are different opinions about it and we as individual we can keep what we believe, as same with you, for me personally I still believe that Jordan still remain as the Goat of this sport like you mentioned if there's a new one then the title will be handover to such athlete but so far there's none as per my opinion.
We have our own opinions are basketball fans, even MJ himself said that he respects the greatest basketball player before him. Unlike Lebron though who says if I'm not mistaken that he is better specially the feat that he come back from a 1-3 deficit against the Warriors and won in the finals.
But in any case, this is going to be a ongoing debate, even those so called analyst and players have disagree at some point as who is the GOAT. Those who have seen the era of MJ tells it's him, while for those who have followed Lebron or watch him play argues that he is the GOAT.
