“If he drags the Cavs to the finals…”
He plays for a team that SHOULD be in the finals. I’m not sure how their getting there should be considered a miraculous act.
“If they win another title…”
I’m a big believer in that old Dean Smith quote after he won his first title: “I’m not a better coach than I was yesterday.” Lebron is what he is. If you think that’s the GOAT, then fine. But nothing that happens next should change your mind at this point.
