    Dwight Howard +6.1
    James Harden +5.63
    Josh Smith +4.98
    Trevor Ariza +3.48
    Corey Brewer +3.32
    Terrence Jones +3.16
    Donatas Motiejunas +.56
    Patrick Beverley +.45
    Jason Terry -.39
    Pablo Prigioni -1.75
    Joey Dorsey -3.45
    Kostas Pap -6.18
    Tarik Black -6.23

    Information on how the stat was created and the ratings for all teams in 2014 and 2015 can be found here:
    adjustedimpactrating.weebly.com

    The base equation in this formula is a linear regression with the output being On Court Net Rating (ORTG-DRTG) for each player and the inputs being:
    TS%
    Opponents TS%
    TOV %
    Opponents TOV%
    OREB%
    DREB%

    I can try and answer and questions about the metric

    How do you convince people to accept that : TJ is a 6X more impactful player than D-Mo?

    You shouldn't look at the scale that way. And TJ missed pretty much all of the rough patch of the season in November-December. D-Mo played heavy minutes during that stretch, playing a lot with Tarik Black and Dorsey, where the team was playing more like an 8-10 seed than a 2 seed. TJ played during mostly favorable stretches of team play. Its up to each person to personally decide how much of that improved team play was due to TJ's return, and how much was other factors like Dwight playing or Smith/Brewer being added to the team

    Stats are for losers. You keep looking at stats, we will keep trying to get wins.

    A CERTAIN STATISTICAL MEASURE DOES NOT ALIGN WITH MY PRECONCEPTIONS AND OBSERVATIONS THEREFORE IT MUST BE WORTHLESS!

    You don't convince people that TJ is 6 times more impactful than DMo, because that's not what this metric is telling us.

    While TJ was on the court in games last season, his offensive rating minus his defensive rating was 3.16. While Motiejunas was on the court in games last season, his offensive rating minus his defensive rating was .56.

    Not only are there a ton of differences between the time TJones spent on the court versus DMo, but you're trying to view this metric as a linear graph of quality. If you want to compare the players as a measure of multipliers, use the source numbers for offensive and defensive rating instead.

    This is a case of understanding what the stats tell us, not blinding accepting it and reaching false conclusions about it.

    +/- stats can't be compared using ratios.

    A middling player might have a +/- of 0, and a slightly above average player might have a +/- of +1. It doesn't mean the slightly above average player is infinitely times better than the middling player.

    This stat tells you don't just look at the stats, but you need to close your eyes and think.

    Or simply put, just don't look at the stats at all.

    OP posting a stats : that includes number and ranking, and without further detailed explanation other than the usage of this stat is for ' impact'.

    So we all understand that Dwight and harden are more impactful player than the like of black, papa, Dorsey. I get that.

    But then when we look at TJ an Dmo who are ranked next to each other and the number obviously had a big gap, what does it tell you?

    Point taken. It says that it does adjust for team mates.
