On Wednesday night, Luka Dončić put the entire Dallas Mavericks organization on his ailing shoulders
Our last post covered rookies four through ten. Today, we’re crowning the 2019 NBA rookie of the year by our z-scoring methodology. The scoring system looks at how a rookie did, relative to every rookie since 2000, and scores their marks for several key per game and advanced statistics. Summing all of those scores up generates one composite score. Holistically, the scores show which rookie had the biggest impact.
Now, let’s highlight the three best rookies of the 2019-2020 season. All data included is from the invaluable Basketball Reference.
The under-appreciated top pick
3rd out of 29
Total Score: 16.53
Rookie proxies: Kenneth Faried, LeBron James, Tyreke Evans, Andre Drummond
Poor Ayton. Ayton’s a thoughtful, dedicated guy stuck in the NBA purgatory of Phoenix. He’s creating a positive impact across the board, with room to improve.. Ayton doesn’t shoot enough free throws and he’s turning the ball over a bit too much.
Despite being the third ranked rookie, Ayton failed to break into the ROY conversation. Ayton’s total production fits right between two previous rookie of the year winners in LeBron and Tyreke Evans. While his defense does need improvement, he would be in the ROY conversation in a ton of other seasons. Instead, he’s been chasing the next guy all year.
The guy who probably wins it in real life
2nd out of 29
Total score: 20.33
Rookie proxies: Joel Embiid, Mitchell Robinson, Nikola Jokic, Anthony Davis
Doncic came in this year as a 19-year old with an unbelievable pedigree in Europe, and he’s been nothing but stellar since day one. He set the record for triple doubles for a teenager. Doncic’s brilliance convinced the Mavericks to accelerate a rebuild with the big Kristaps Porzingis trade,.
Luka takes on an incredible burden offensively for the team while still involving his teammates. Per Basketball Reference, Oscar Robertson is the only other rookie, ever, who scored over 20 points, gathered 7+ rebounds, and dished out 5+ assists.
Yet, somehow, our scoring has him as the silver medalist in the ROY race. Who wins the prize?
A fun, exciting surprise at the top
1st out of 29
Total score: 21.04
Rookie proxies: Karl-Anthony Towns, Joel Embiid, Luka Doncic, Nikola Jokic
Spoiled a bit by the Luka proxies, Robinson ekes out the top spot in the 2019 rookie rankings. Big Meech stands next to “cap space” as the most promising asset for the Knicks in a particularly brutal season, and the 2nd round pick has shown game-breaking promise on both ends of the court. Robinson’s blocks shots at a rate four full standard deviations above the mean for rookies, the second-best score for blocks for any rookie since 2000, after Joel Embiid. Advanced metrics adore his efficiency–even in a cataclysmically bad Knicks season, he still produced the highest box score plus/minus of any rookie in my dataset.
Don’t take just my word for it. Mike Vorkunov profiled the young phenom in this great piece, diving into the thought process behind his defensive acumen. The Knicks’ subreddit now traffics almost exclusively in Robinson fandom. Tommy Beer wrote up some other statistical breakdowns for Robinson, stoking the hype even higher. Mitch combines a nearly endless upside on the defensive end with glimpses of offensive effectivity, and for a second round pick, the Knicks found a gem.
Are you seriously saying he’s a better prospect than Luka?
Let me take off my Nate Robinson Kryptonate jersey and assure you that no, I am not arguing that Mitch should win over Luka.
Mitchell Robinson might not place third in the final tally. His rank here highlights a potential oddity with the scoring methodology, and deserves a closer look.
Let’s look at the two players side-by-side.
You quickly see that both guys trend in similar directions across most stats. Robinson’s insane blocks per game matches Luka’s scoring prowess, and both bring above-average impact to the box score differential and PER.
Yet, this graph accentuates a couple data points that actually make Luka’s case for him. Luka has a usage rate three deviations above the average rookie, third only to Joel Embiid and somehow Ben Gordon in my dataset. He’s asked to do a ton for the Mavericks, but he’s still able to play effectively. with a high true shooting rate, and produce a well-rounded statline; his high marks for assists, steals, and rebounds hint at the all-around game that inspired my favorite Ringer song. Really, the only mark that brings our boy down is his incredibly high turnover rate. Like his counterpart Trae Young, Luka’s high offensive workload produces more turnovers than the typical rookie, and with a bit more seasoning and an improved surrounding cast, he’ll be poised to right the ship in 2020.
Luka and Mitch represent similar total scores, but their value is derived in fascinatingly different ways. Mitch projects as a Rudy Gobert/Clint Capela style big, wreaking havoc on opposing offenses and scoring efficiently when he’s called into action. Luka’s a bit more challenging to predict: every time I watch, I’m convinced he’s James Harden without the foul rate, and if you catch me on the right triple double night, I’ll swear we’re watching a version of a less powerful LeBron with a deadly jumpshot.
Either way, I’m incredibly excited to watch both players grow and evolve, and we’re blessed to have yet another fantastic draft class. Check out the list of all rookies here, and be sure to subscribe for our next contentious analysis: who’s the MVP?
