well TS% is not really an advanced stat, unless you think slugging percentage or OPS in baseball are advanced stats. I think this is a great comparison though, Effective field goal rate = slugging percentage (accounting that 3s are more valuable than 2s, just like a home run is more valuable than a single.) while TS% is essentially OPS because it adds on the free throw shooting part (which is almost exactly like walks in baseball. thus on base percentage.)
Yeah, I think Winshare's a flawed, especially on the defensive end. but on offense it's actually very good, but that just kinda goes back to the dilemma that we really don't have defense figured out in basketball. (this by the way, is also true for baseball, but it helps a lot that pitching makes up for most of the defense in baseball so that's easier to assess.)
RAPM is interesting, but really must be viewed in a larger sample to be really relevant . I think they need to do more to break down that stats in terms of 3 year average or splits. WARP is really still in the developing stages,
it should be noted that in baseball WAR / WARP has really became the mainstream among stats savvy fans, also, the 2nd post's definition is wrong, replacement level player is not average player, a team with 14 average player will have a 41-41 season obviously, replacement level player are guys who are fringe NBA rotation players, guys who you wouldn't go "omg he should totally be out of this league" all the time. (assuming you are not totally biased against him.) . but would keep going that "I wish he only played in garbage time" as the later post pointed out, the current definition of replacement level in basketball, if you have 14 such player , is like a 10-72 win team, aka the 76ers next year.
I think WARP in basketball is more problematic though, because in baseball players aren't really influenced as much in their end results by teammates, but in basketball, it is quite obvious the role players' result is heavily dependent on the team they're playing for. this is reflected well in Winshare, where Kevin Martin / Mario Chalmers had a 7 Winshare last year, which is borderline star. but in reality if they were on the Rockets they'd probably be more of a 4-5 win share type player . a true lead star player like Lebron / Harden / Love 's line won't be effected that much by their team (example, Love still had a 10 + WS on bad wolf teams.) unless they have too many stars who are better that forces them down into a more role playing role (aka Chris Bosh.)
