After posting “DMX draft rankings” on social media accounts and referencing the metric frequently on this blog, some have begun to ask “what is DMX?” Fair question! I once tried to explain it in an article breaking down last year’s international prospects, but I made so many wholesale changes to the model that the article became obsolete and I took it down. So let’s try this again.
When I began blogging about the NBA draft, I leaned heavily on NCAA statistics since I am not a paid scout and I saw it as an objective approach that had worked for some sharp draft analysts. The problem I ran into was there were so many trade-offs between each prospect that when it came to ranking players outside of the lottery, let alone the second round, it was like splitting hairs. What I wanted was a literal equation to supplement the one I was trying to do in my head, which gave way to “Draft Model X”.
While I think the DMX results are interesting, the process behind it isn’t overly scientific. To grade each player’s Per 40 minute stats I used Kevin Ferrigan’s DRE Daily RAPM formula and catered it to draft prospects (greater emphasis on steal rate, for example). To give context to those stats, I adjusted each player’s statistical grade (their “DMX Per 40”) for age, height, playing time, and NCAA strength of schedule (via KenPom). I kept the international model the exact same, only I assigned SOS values for international leagues by using FIBA stats to estimate their level of competition relative to the NCAA. I then tinkered with the weight of each adjustment based on previous drafts, which produced the current version of the model. Save for a handful of outliers, each prospect is assigned a grade between 0-10, with the average for drafted players being just over 4.
The greatest testament to DMX is that the very top of the list is littered with hall of famers, all-stars, and future all-stars. Even the misses were top draft picks who failed arguably (or in Oden’s case, definitely) for reasons other than their basketball skills. There’s also the curious case of “Ground Jordan” Adams, who probably would’ve been a steal for Memphis had he been able to stay healthy.
2017 NCAA Rankings
Since several international leagues are still ongoing, I’m going to focus on this year’s top 25 NCAA prospects. They are good. By DMX this is easily the best draft class of the one-and-done era with thirteen players earning top-five level grades:
I’ve already shared my thoughts on Lonzo Ball this year, but I couldn’t let his absurd DMX go without mention. Not even LaVar Ball is as bullish on Lonzo’s NBA potential as DMX. Ball’s mark puts him at #5 all-time between Kyrie Irving and Kevin Love, perhaps lending some credence to the “next Jason Kidd” hype. Though I still think Markelle Fultz is the #1 prospect, Lonzo was the guy who I couldn’t take my eyes off of this season, and I might look back in a few years and wonder how I missed the signs.
The Center Field
Big men are viewed as the weakness of this draft, so it is notable that there are three centers in the DMX top ten: Zach Collins, John Collins, and Justin Patton.
Collins was a key component to Gonzaga’s best team ever and is easily the best C in this draft class. Few freshman have ever scored, rebounded, and blocked shots at the rate Collins did, and if not for turnover issues he would have totally crushed DMX. He’s probably in my subjective top ten.
Wake Forest product John Collins (no relation) has the same DMX as Zach Collins, but is a more dubious draft prospect. His case as an ACC PER beast who doesn’t shoot threes or defend is most comparable to Jahlil Okafor and Carlos Boozer.
DMX definitely overrates J. Collins, however it is inarguable that he was one of the most productive and efficient teenagers in major conference NCAA history, which should probably count for something.
In addition to his stellar DMX projection, Patton was dominant when I watched him play against Butler and Georgetown. He is an amazing roll man and lob-catcher on offense, and flashed the ability to change shots and defend pick and rolls on the other end. I see him as a version of Brandan Wright who can potentially step out and make jumpers.
The Reverse One-and-Done
Derrick White spent three years playing at Division-III Colorado Springs before sitting out a year as a transfer and finally completing his college career with a lone D-I season at Colorado. That means White’s stats aren’t weighed down by previous seasons like other NCAA seniors, but the adjustments for age and strength of schedule (for D-III seasons) should offset that advantage. Oregon’s Chris Boucher is a JUCO transfer with very good NCAA stats, and is not in the top 60 of DMX. The reason Derrick White still grades out so well is that his one NCAA season was epic, even compared to other senior guards.
White finished the season with back-to-back 30 point, 5 rebound, 5 assist games against Arizona and UCF (#18 ranked defense), which would be pretty good for an NBA player dropped onto a college team. My preferred theory is that White is not a small sample fluke, but rather a guy who slipped through the cracks before getting a chance to show what he could do in the Pac-12. He’s got a spot on my big board.
