I've never been impressed by it as a stat, seems very much for single players trying to individualize something that can't be easily individualized, and for both players and teams quantifying something that can't really be quantified. I dunno, I've looked at some of the formulas and don't really find them terribly impressive, but maybe I'm wrong.
Also, my understanding is that individual Drtg is something akin to raw +/- in that it does not adjust for teammates, correct? If so, that makes it even less close to the mark. Maybe this is another discussion entirely, for the Stats board...
Well, I like WS, though I wouldn't want to put too much stock in it. It's got that classic all-in-one pro/con where it sums up a lot in more number, and thus is a good snapshot, but it also combines very different things, so it's probably better to have all those different numbers handy. Still, I like those snapshots, and there was dire need for really anything that measures total impact (as opposed to per possession played impact).
There's also the matter that on defense, it seems bound to underrate guys who don't rack up box score stats - that said, for guys like that on good defensive teams, they're getting more credit by WS than anywhere else (save +/-).
One of the reasons it's getting used so much in the past, is that it's not so easy to get those numbers separately way back in history. This is unfortunate on a number of levels, one of which being that WS are far less accurate back then due to the stats not recorded. However for that issue, I'm just always making some adjustments in my head. For example, Walt Frazier did really well on WS, despite the fact he almost certainly had steals beyond what WS estimates, so there's reason to believe he was actually underrated by WS - so I've got no majors issues using WS for someone like him.
Re: DRtg. Having trouble thinking this through at the moment. I'd tend to think of DWS as largely about converting DRtg into a format where total accumulated impact is measured instead of per possession impact, and then normalizing it so that it could be put in terms of wins. So neither is really more off the mark than the other, just depends on what you're trying to ascertain. Others thoughts?
