It's true, I'm kindof an ass too.

We're both passionate about our opinions, I can appreciate that. It's nothing personal of course. And I could probably stand to be more open-minded about a lot of things. Especially right before I go to bed when I get downright hostile for some reason. I'm happy to call you my friend -- sorry about the snark.
Some of your arguments though are downright confusing to me. FG%
does include 3pt% -- it includes everything except free throws so I don't think it's useless if you're measuring the quality of the shots a team is getting. Of course it doesn't account for players being wide open and missing anyway, but hopefully over the course of a season that evens out a bit league-wide. That's where common sense comes in. If you know you have a team of non-shooters you can't really blame the guy passing the ball for the low team FG%. I'm not talking down to you for using TS% -- I just don't appreciate people talking down to me as if FG% and 3PT% are for bar rants only and the educated folks are using TS% these days. I flat out don't like it as a stat. The whole discussion of the shooting charts was me trying to demonstrate why. It's counter-intuitive to say "this guy is actually worse, you're just using the wrong stat" when it's quite plain in black and white that the player with a higher TS% (both players in this case) missed more shots from the floor than the player with a lower TS%. For my purposes, FG% and 3PT% are much more useful tools. They isolate exactly what I'm trying to talk about without the statistical noise of poor free throw shooting factored in. And in terms of assisted baskets it is statistical noise because free throws typically don't create assists (unless it's a 3pt play but that becomes a lot more work to calculate -- I have a full-time job, and I'm not trying to win the stat Olympics).
DBPM and DWS aren't better stats than BPM and WS in a vaccum, but if we're trying to isolate a player's defensive contributions than they're not just better, it's apples and oranges. Overall BPM and WS factors in a player's offensive contributions as well so they're useful for measuring a players overall impact on the game but useless for measuring their ability as a defender. I don't discount your defensive rating, I just don't know anything about what NBA.com uses to calculate it and I've always used Drtg from basketball-reference.com. I'm sure it comes across sometimes like I'm just interested in winning an argument but that's not my personality. I don't want to talk people into agreeing with me, I want to be correct. I'm obsessed with the truth. I use the stats I know because I can tell when there's an outlier and how to account for it. I don't know anything about defensive rating from nba.com so I don't use it. And I don't know anything about real plus minus because ESPN doesn't want me to know. It's not that I dismiss it when I don't like the results, I dismiss it for everything across the board. It's not falsifiable therefore it's not scientifically permissible.
Maybe this is just semantics, but do you agree that Steve Nash deserved his MVP awards? Is it possible to be an MVP without leading your team in scoring? You make it sound like that's a contradiction in terms and I don't see why assists should be considered less important to the team than points. By definition every assist includes a made basket. If you're going to dismiss assists, rebounds, and steals outright and say "prove to me Rondo is a better player using something else", I just don't understand the point of the question. Why should I want to do that? Andre Drummond and DeAndre Jordan are both terrible free throw shooters. They can't create their own shot nor do they create a lot of shots for their teammates. What they do is rebound the hell out of the ball and block shots. You're going to tell me those contributions aren't important? Do their teams have to play a certain way to accommodate a player who can't dribble the ball or shoot beyond 15 feet? Yeah I suppose they do. And yet that's a sacrifice those teams are not only willing to make, they'll pay max money for the privilege of handicapping their team in that way.
What that indicates to me is that there is no single metric which can be used to sort every player in the league. Some players are elite shotblockers and rebounders, some are elite shooters, some are mediocre shooters but elite scorers because of their ability to force fouls and convert at the free throw line, some are elite individual defenders, and some are elite playmakers. How are you going to compare an elite shotblocker like Hassan Whiteside to an elite scorer like James Harden and say which one is better? It doesn't even make sense to ask that. If you want interior defense, Whiteside is a better fit. If you're having trouble putting points on the board maybe you invest in Harden instead. Maybe Conley and Holiday have more diverse overall games but you have to acknowledge that trading out Rondo for either one of them means losing something in certain areas (playmaking, rebounding, and as far as I can tell, team defense as well) while you gain in shooting ability and ball movement. And frankly, Rondo shot the 3 ball better than
both of them this season so it's even less obvious to me that either one would actually be an upgrade.
It feels like our arguments are just sliding by each other in parallel though. I show you every metric I use and you dismiss all of them. Then you show me every metric you use and I dismiss all of them. We're never going to come to any kind of agreement like this. You seem a lot more comfortable with advanced stats than I am, which is fine. I'm old-fashioned in the sense that I want you (or really anyone) to prove it to me why I'm supposed to use your metrics instead. Are counting stats flawed? Sure. Are defensive ratings universally accepted? Not even close. But we're not talking about a few points of difference here. Rondo was the league leader in assists (by a large margin), he was 7th overall in steals, he was #2 in rebounding among all PGs (and basically tied for #2 among all guards). These are significant and important parts of the game in which he has demonstrated over the course of his career that he's among the best in the league. Why should the burden be on me to
prove to you that he's better than two starting PGs who aren't elite in any skill areas?
