Which NBA Teams Are the Best at Drafting?
And which usually pick the wrong guy
What a turn of events for the Pelicans. After last year’s Anthony Davis trade fiasco and uncertainty surrounding the team’s front office, New Orleans looked to be in free fall. But winning the 2019 draft lottery—otherwise known as the Zion Williamson Sweepstakes—has catapulted their prospects. Throw in their extraordinary haul for Anthony Davis, and the Pelican’s future looks as bright as anyone’s.
Not every team can bank on some ping pong balls falling their way, though. Drafting well is a tricky but essential part of building a team, whether it be to choose players that will develop into superstars, or into assets to land superstars. Choosing player A over player B could be the difference between contending for a championship and finishing middle-of-the-pack. So which teams have historically made the right pick?
One way to measure draft success is by comparing a player to those drafted after him. In 2011, the Kings took Jimmer Fredette at pick #10. Next came Klay Thompson, Alec Burks, Markieff Morris, Marcus Morris, and Kawhi Leonard. They passed on two superstars, and two competent role players. Not great.
We can use this line of thought to judge every draft pick. By comparing the success of a player to the five guys drafted next, we can get a sense of how good the pick actually was. How will we measure "player success"? For this project, I used VORP, an advanced analytics stat. The higher the VORP, the better the player.
Here’s Jimmer score with our methodology:
Jimmer clocks in at -11.7, which makes him the 24th worst draft pick in the last 20 years. Oof.
Distribution of Draft Scores
Jimmer might have been one of the worst, but who were the best? LeBron leads the pack, which might come as a surprise to some—the five players drafted after him include future Hall of Famers like Carmelo Anthony, Dwayne Wade, and Chris Bosh. But LeBron is such a statistical anomaly that the players drafted after him are virtually meaningless; his raw score is just that high.
The rest of the top 20 features other bonafide superstars, but it also includes players who were taken later in the draft and greatly outperformed expectations. See: Kyle Lowry.
The Best, and Worst, NBA Draft Picks Since 2000
Now let’s look at teams. If we take the average score of a team’s picks over the last 20 years, we can determine its overall success in the draft.
The Pelicans come out on top as the best drafters, a little surprising given their lack of recent playoff success. But that isn’t because of their drafting—the Pellies are known for botching the Chris Paul and Anthony Davis eras by whiffing in free agency.
The Cavs, buoyed by LeBron, and the Thunder, who drafted Kevin Durant, James Harden, and Russell Westbrook in three consecutive years, round out the top three. The rock-solid Spurs also bubble towards the top. They’ve drafted the best since 2010 despite having the worst average draft position in the NBA.

Twenty Years of NBA Picks, Visualized
Each team, and each pick, has its own story. When did your team’s front office strike gold? And when did it cripple the franchise by blowing a top five pick?

How to read this chart
The data for this project comes from Basketball Reference. I grabbed every NBA draft pick from 2000 to 2018, and standardized the data in the following ways:
- Multiple franchises have moved cities or changed mascots since 2000. For consistency, I updated every player’s data to reflect the current iteration of their franchise. That’s why you see Kevin Durant drafted by the Thunder rather than the Supersonics, for example.
- Basketball Reference does not account for draft-day trades. Because a team that trades for a player on draft night usually has a say in the actual pick, I updated every player’s team to be the one that they started the season on.
- Players who were drafted but never played in the league have no VORP score. I assigned these players the average VORP score for their draft position over the 18-year period. The reason for someone never playing can vary, so this felt like a fair way to deal with it programmatically.
- Players who had less than five players taken after them (i.e. picks 56 and higher) were omitted.
I chose VORP for the basis of this analysis because I believe it’s one of the best all-encompassing metrics out there. If you think this analysis would be more effective with a different metric, or a combination of metrics, please reach out!
