I don't think it's meaningless at all. As a matter of fact, it's my favorite stat. It shows your true value as a player, because after all, isn't it about getting more points than the other team? Also, it shows the value of guys that aren't volume shooters/scorers and who do the other things, the little things. Like rebounding, defense, overall cohesiveness and glue. The things that aren't given as much attention.
