    Turnovers, bad D, and giving up O rebounds reduce our possessions

    All these numbers mean is that we employ a risky strategy that either succeeds or fails, period, and is much more likely to fail when you play teams that guard the perimeter.

    Not that I'm accusing you of this, OP, but people always seem to forget that games are won individually to build a good record. Average stats mean nothing. Consistent stats mean something. I've never seen such an inconsistent team as these Rockets have been over the past few years, even when they keep winning. The standard deviations on so many of their stats have got to be enormous.

    HeyP, is the answer not found in Harden and ft made?

    Not a shot, but 1.75 points per trip to the FT line (and 1s are a shot, so they are 2.87 pps - or 3.87!)

    We are 2nd in the NBA in fta and ftm. I guess the Twolves (1st in makes), and Clips (1st in flops), are ahead of us in points per shot?

    Check the correlation historically between TS% and Win% vs PPS and Win%.

    Code:
    [B]      2011    2012    2013    2014    2015    2016    Total[/B]
    TS%   0.762   0.734   0.740   0.726   0.845   0.609   0.776
    PPS   0.732   0.702   0.737   0.698   0.756   0.555   0.728
    
    That means, since 2010/2011 season, TS% has a higher explanatory power than PPS for games won vs lost.

    Correlation doesn't mean causation.

    Just too many turnovers. When we get shots, they are usually good shots. But this team is way too turnover prone that they can't consist get good stretches of shots. There's always a turnover to ruin our rhythm and get the other team back in the game.

    It is evidence for causation, even if it doesn't imply it.

    But we can look at the constituent parts of TS% and understand its relation to Win%. What "causes" a team to win its game is that it scores more points than the opponent. We know a team is much better positioned to score more points than its opponent if it is scoring a higher number of points per possession, because possessions are more or less equal between the two teams. So, we can say that how efficiently a teams scores on its possessions does have a strong causal relationship with the end outcome.

    TS% tells us how efficiently a team uses its possessions in which the ball is not turned over and there are no second-chance scoring opportunities. That's a fairly large percentage of total possessions. That's why TS% matters for wins vs losses.

    PPS also tells us how efficiently a team uses its possessions, but it disregards how often a team gets to the free throw line. It ends up being a lesser quality indicator of overall team efficiency as a result.

    Is that the league or the Rockets? :) Remember, I said "Interesting Stat," Note, I was never disagreeing with TS%/eFG%. Nor was I saying it's has a better correlation with Wins. I was remarking to someone who said that PPS means nothing, and said "It's a fine stat." So, yeah, I agree with you, just not the person who said PPS means nothing.

    anyhoot, I've always been more interested in PPP. That is even more useful. Don't know why that isn't represented more in Adv Stats, especially since SportsVU data could track it very easily, and without the .44 generalized multiplier.

    what is the definition. there are conflicting views in this thread. I always thought it was simply PTS/FGA.

    The stats I posted were league-wide, season-by-season. Each year I calculated the correlations across all 30 teams.

    I assumed also PPS is PTS/FGA, as opposed to TS% which is PTS / (FGA + trips to FT line not including and-1s and techs). Using .44*FTA is very accurate at the team-level, by the way -- I wouldn't be concerned over that.
