Jordan easily, and I mean easily has all the tools. He’d be a completely different player in today’s era I would go as far as to say a first team all defensive player no doubt.

But that’s a hypothetical. His skill level never was maxed out defensively because his competition was nothing like today’s perimeter talent aside from a few guys.

Iron sharpens iron. Going up against Kobe, Wade, kemba, Kyrie, dame, Kawhi, night to night to night is nothing like anything he faced.

He primarily could free lance and rest off his man who wasn’t usually a threat to shoot or score off the dribble while the guard on the other side dropped the ball into the post.

He was a gambler in an era of much inferior ball handling and passing. Great in the passing lanes, but also got burnt a ton and walked back on defense too often.

He was often very lazy to contest shots. Even to stunt. His footwork was very primitive defensively. He wasn’t the strongest. He had poor discipline. And this goes throughout much of his career. His defense was much better in the late 80s.

One more thing to point out. Reason I list possessions is it helps account for VOLUME. Good defenders will typically log more possessions.

0.67 Pat Connaughton (73 poss)
0.77 Wesley Matthews (287 poss)
0.78 Paul George (316 poss)
0.83 Josh Richardson (181 poss)
0.86 Marcus Smart (249 poss)
0.86 Jaylen Brown (136 poss)
0.91 Kyle Korver (188 poss)
0.91 Jordan Clarkson (191 poss)
0.93 Zach LaVine (137 poss)

Smart and Brown play the same position on the same team and Smart has logged 113 more Iso possessions. If we take away Smart's 2016 season (Brown wasn't in NBA):

0.83 Smart (187 poss / 6,213 minutes / 1.08 poss per 36)
0.86 Brown (136 poss / 5,406 minutes / 0.90 poss per 36)

This informs us that Smart is being leaned on more heavily as an Isolation defender.


On the other end of the volume spectrum, while Pat Connaughton has a great rating, his low possession count indicates he isn't really getting the call in these situations. While he's certainly a quality defender, he's usually playing with the bench unit where Isolations are less likely to occur.

Paul George's rating/volume meanwhile is absurd.

Yes, I also struggled on players having lesser 'attempts' like having less than 10 3s but shooting an enormously high 3pt percentage. So in this context, should we filter the possessions, followed by iso? That would give a more realistic representation on the ratings/tendencies.

[Real2KInsider]

Consistency ratings affect player heat - which in turn affects various ratings across the board. By itself it does nothing.


Currently compiling SF data, this shouldn't be surprising but Isolation defense is far more important here than the other perimeter positions.

[TheDominator273]

So if perimeter defense is just shot contest ratings shouldn't the corresponding statistic to look at be something like this. https://stats.nba.com/players/defens...PerMode=Totals

Only filter applied is for Games Played to be 41 or more but you could filter by a certain number of contested shots instead simply as a way to ensure the data you look at has the small sample outliers taken out.

But with how I have it filtered, Gary Harris has the biggest differential between opponents FG% vs what they shoot when he is defending (shots greater than 15 ft) with a -10.4% differential, yet he only has an 82 perimeter D rating as shown above.

To compare, Eric Bledsoe who has a 93 perimeter defense and sports a -0.3% differential. At the other end of the spectrum Trae Young had a +2.0% differential and has 55 perimeter defense.

[Real2KInsider]
