PostPosted: Tue Nov 14, 2017 11:10 am    Post subject: Team's RPM Numbers

Since it's not possible to trim down the Lakers players RPM values at ESPN.com I sorted it out of personal interest earlier and am sharing the list for anyone else who is interested. I'm personally not a huge fan of +/- stats, though if you are going that route RPM is a reasonable way of doing it. Read into these what you will, just posting the numbers.

Randle: 1.99
Nance: 1.01
Bogut: 0.65
Zubac: 0.49

Clarkson: -1.4
Ennis: -1.49

Zo numbers contradicted my expectations. I’m happy for Randle though and his defensive impact. Kuz and Ingram defensive impact does not reflect my eye test.

Not 38, but the majority at center. He's the best two-way player on the team.

What was Lopez's RPM last year? I imagine a lot of why he's at the top right now is a prior from last year. This ranking might suggest Julius has been better overall, because Julius's prior from last year would be dragging him down.

Fellow gear head appreciates this comment. But dang 2 to 3 rpm?- must be a really large displacement diesel or a steam engine.

I consider you the expert on this. Does it also factor who they're playing against? Inferior bench players vs. starters.

Yeah, that's what it's supposed to do. Of course, how good it is at successfully adjusting for opponent quality is a question. I find it does a pretty good job at that, though.

Ingram's RPM was one of the worst in the league last year. Ingram will need to sustain his improved play for longer, in order to convince RPM that he's actually much better this year than last.

A couple general comments about RPM:

1. Beware of using it to compare players in different positions. This is because the defensive component (DRPM) will almost always greatly favor big men. This is legitimate, because the big guy standing next to the basket is likely to have a greater impact on defensive performance than the little guy out on the perimeter. You can see that in the numbers that J.C. posted.

2. In that respect, Ball's DRPM is actually extraordinary for a rookie. I posted about this in the Ball thread this morning. 0.54 ranks ninth in the league in defense by a point guard. Ball ranks ahead of some veterans who are generally considered to be good defenders. By comparison, Fox ranks dead last among point guards in DRPM.

Thank you for posting this, JCS. Since the RPM data doesn't have splits, I propose we keep a record of RPM changes month by month in this thread to track players' progress.

On reflection, the only numbers on the chart that really jump out at me are the ORPM numbers for Clarkson and Kuzma. I would have expected them to be a bit higher.

I’m also struck by the mediocrity of Casey P.’s numbers, though I’m not surprised by them. Detroit knew what it was doing when it picked ups Bradley and let Casey P. walk. If Casey P. doesn't get it going, he is going to regret turning down $80M/5 years from Detroit.

Great point. I like to compare point guards and win% for Lonzo because he doesn't score much but his win% has greater impact.

Yes, though it is far from perfect. PER and most of the common measures are based on box score stats, and we all know that box score stats are limited in basketball. DRPM is the only measure of defense that (mostly) passes the eyeball test for me. I wouldn’t treat RPM has some sort of talismanic stat that is the embodiment of Truth. Also, as I said before, you should not use it to compare players who are not comparable (PGs and Cs for example). It requires some degree of interpretation as a result. With that in mind, RPM is more reliable than PER and the other composite box score stats.

Edit: Another way of expressing this point is that RPM does not purport to be a measure of player value. An average center may have more defensive impact than a good defensive guard, but the guard’s defense maybe more valuable because a center can’t play guard. You can replace an average center’s defense with another center, but it may be really hard to replace the defense of a good defensive guard.

Looks like RPM is having a hard time moving on from the Russell trade.
