Alright I'm with you there, it's not an official scale by any stretch. But it's hard to completely deny the general accuracy of it. James, Kobe, Wade all those guys are 1st ballot HOFrs. Ray Allen really is just on the cusp of super star (barely getting voted in the last 2/3 years). I mean for the vast majority of the player overalls, this scale is a solid way to get a sense of where I player stands regarding the rest of the league.
Also I wouldn't say overall's are predetermined. There should be some reason for general consensus Say Dirk is an 83. Right now he's an all star. Not the MVP he was several years ago. Not All First-team any more. But an all star. I mean, I'd say that's a true statement. We know the individual stats somehow calculate the players overall, even if we're not sure exactly how they weight it. But if Dirk as an 83 is legit, and his rebounding isn't that great and his defense is certainly terrible, then he's gotta be amazing in other areas. Amazing shooter, amazing free throw guy, solid handles for a 7 footer... The reason he's not a high 80s guy is BECAUSE his rebounding and defense are low.
I dunno maybe I'm misunderstanding your question/point. Would you say it again differently for me?
