That’s not really true. I’ve actually posted Taylor’s AuPM/g numbers—which have Steph Curry leading the league every season for 6 straight years. And I’ve addressed Cheema’s numbers, which have Curry leading the NBA in two five-year spans during LeBron James’s prime. Not sure what the Englemann numbers are, but the other two support my point!
Leading in two 5 year spans doesn’t make Curry “the king of the databall era” when the highest 5 year spans belong to Lebron (as well as the highest PS only spans) and include some Curry’s best years, i.e., 2012-2016, and 2013-2017. 2014-2018 Curry was higher than 2014-2018 LeBron, but not higher than three separate 5 year spans by LeBron, i.e., 2006-2010, 2012-2016, 2013-2017. Lebron also has 8 of the top 23 five-year stretches, 10 of the top 30. Curry has 4 of the top 30. Not sure how you can say “regularly” when 2017-21 LeBron is lightly ahead of 2017-2021 Curry and 2016-2020 LeBron is ahead of every Curry stretch other than 2014-2018.
Curry does really well in the AuPM numbers, but James sits atop those numbers so not sure how that supports “king of the databall era.”
But here you’re the one comparing RAPM numbers from different timespans, which you’ve otherwise labeled as made up data. The reality is that prime Steph overlapped with prime LeBron, and he outdid prime LeBron James in two different five-year spans in the Cheema data. And the Cheema RAPM measure is less bullish on Steph than the NBAshotcharts or GitHub RAPM.
Steph also outdid LeBron in a boatload of other data. I summarized a lot of it here: viewtopic.php?p=107531004#p107531004. We find that Steph in his prime years (i.e. 2013-2014), Steph outdid LeBron in:
1. Every NBAshotcharts five-year span starting with 2013-2018;
2. In GitHub RAPM for every regular season
3. In 4 out of the 6 playoffs they both played in, by GitHub RAPM
4. In RPM in 8 out of 9 seasons
5. In regular season RAPTOR in every single season
6. In playoff RAPTOR in 5 out of 6 playoffs
7. in 6 out of 9 seasons in LEBRON
8. In two five-year spans of LeBron’s prime in the Cheema RAPM data
9. In AuPM/g in six straight seasons from 2013-2014 to 2018-2019 (which I posted about yesterday: viewtopic.php?p=107640153#p107640153).
10. In AuPM/g in 4 out of 6 playoffs
This is an absolute boatload of impact metrics and impact/box-score composites that have prime Steph Curry outdoing LeBron. Obviously, in some data sets, he outdoes LeBron by more than others. For instance, the Cheema RAPM is less bullish on Steph (or rather, maybe more bullish on LeBron) than the NBAshotcharts RAPM. But Steph looks good in all of this stuff, and the overall picture definitely goes Steph’s way.
Please also note that the quote of “king of the databall era” is not a real quote. I was pretty sure I never said that, and I just searched my posts and did not find it. I have said that prime Steph usurped the databall crown, and what I mean by that is that in his prime he was the king of databall metrics. I was not asserting that he was superior overall than LeBron (i.e. not necessarily that prime Steph was better in databall metrics than LeBron was before Steph’s prime). That’s a different question that we’ve already established is essentially impossible to answer properly. But their primes did overlap significantly, and Steph did outstrip LeBron during that time. So yes, in that sense he did become the databall king, but that’s a bit different than being the “king of the databall era,” which is not something I ever said.
They were posted in this very thread 3 posts up in a post you replied to as well as posted other times by other posters that you seem to never respond to.
No need to be rude about it. I replied with a general response to your point, without looking at every source you’d posted, since your point was not actually source-specific.
Anyways, while Steph gets above LeBron in some years in that Engelmann data, that’s definitely more bullish on LeBron. Ultimately, though, Steph was above LeBron in the last three seasons in the data (i.e. 2016-2017 to 2018-2019), while LeBron was above Steph for the first three years of the data that encompassed Steph’s prime. So it’s one of the better pieces of data for LeBron, but it doesn’t exactly refute the idea that prime Steph outdid prime LeBron. Put it in the list of other stuff I listed above, and the overall picture is still very much in Steph’s favor.
Finally, I’ll note that I don’t think that the 26-year and 25-year Cheema samples get to this precise question. They’re very helpful and interesting in general, but I’m not asserting that Steph was better in impact data on average over the course of his career. I don’t think that’s true! Steph started more slowly than LeBron and those years make up a decent portion of his career. So I don’t think it’s at all mutually exclusive that LeBron would be ranked higher in a career-wide average, even if Steph outdid LeBron during Steph’s prime. Indeed, the data we have overall supports both premises.
As mentioned to you several times, NBA ShotCharts data doesn’t include the playoffs, but Curry does really well in them, so I’m not sure why you posted “average“ RAPM numbers that do not exist.. Steph Curry’s numbers look great but Cheema’s numbers do not support the position that “Steph Curry has Outstripped LeBron in impact metrics.” I see what you’re saying about a direct comparison point because they’re playing at the same time (same players in the league, etc.) but you cannot be the king of the databall era by having marginally higher numbers in a few spans, when the other players has the best numbers overall and the overall highest 5-year RAPM spans AND 5 year spans in his 30s (i.e., 2016-2020 and 2017-2021) that are higher than the ones in Curry’s prime.
Again, as I posted, average RPM/average RAPM is nonsensical due to how RAPM is calculated. On a board such as this that values data and nuance, made up data doesn’t further discussion. We have 5 year intervals we can look at.
Perhaps I’m missing something here, but simultaneously saying you can’t average RAPM or RPM data across different years, while also specifically making a direct comparison between LeBron James’s RAPM numbers in one interval to Steph’s RAPM numbers in other intervals (i.e. saying LeBron has “the overall highest 5-year RAPM spans”) doesn’t really make much sense. Either you can compare RAPM numbers across different timeframes, or you can’t.
