In most cases, I’m not a fan in dealing with black-and-white absolutes. Records that are seen as impossible to break get broken. A player is deemed the best ever, only to have another come along and do everything better than their predecessor. “Never” is seldom an accurate statement in the sports universe.
Keep in mind that a player may come along or even already be in the NBA who can replicate Malone in one or even two areas, but there is not nor will there ever be a player who can do everything Malone did as well as he did it for as long as he did it.
