The 2020 NBA draft combine, which was conducted virtually this season due to the ongoing pandemic, has yielded some very wonky results.
Rather than traveling to one central location like previous years, prospects are getting measured at the NBA team facility that is nearest to a player’s home or their interim residence. Medical testing and examinations were performed by NBA-affiliated physicians in the same market.
That means that results are trickling in rather than coming streamlined on the same day, as usual. It also means that while the league is taking measures to ensure that everything is as consistent as possible, there are some inevitable inconsistencies when comparing year-over-year testing.
One reason could be that these prospects have had far more time to prepare for the combine than players have had in other seasons due to the draft being pushed back five months. But now that certain scores have been reported, some are drastic enough to cause serious eyebrow-raising to the point where we knew we needed a deeper dive.
Will just note that I have some general skepticism about some of the NBA Draft Combine numbers floating out there. Not that they’re being reported wrong, but more about the methods of measurement and the lack of singularly consistent entity doing the measurement.

This has been most apparent when looking at results for the shuttle run this year. For example, speedy guard prospect Devon Dotson improved his score by 0.58 seconds since tested last season.
Earlier today, we speculated that the shuttle run may have been measured differently this season as it was unlikely that (at least) the four fastest shuttle times in history all would have been from the same draft class. Fortunately, however, we received some clarification as to what may account for these eye-popping changes.
Shuttle runs times are typically based on reactive pro agility; a light goes off and the prospect completes the drill in the direction of the light. According to someone who spoke with USA TODAY Sports Media Group’s Rookie Wire on the condition of anonymity because they were not authorized to speak publicly on the matter, this year, the direction of the run was predetermined for the shuttle run before the drill began and no lights were used.
For comparison, you can watch participants complete the drill in the video above and see that they are being judged on split-reaction time. Previously, the drill started when the light went off and the direction of that light (left or right) was randomized.
But not every team facility had access to that equipment, so to make sure that the drill was standardized, no lights were used. Instead, prospects were told which way they were to run ahead of time.
“That could easily change the time by a few tenths of a second,” one trainer, who has helped pro prospects prepare for the NBA draft, told Rookie Wire.
Eliminating the reaction time contributed to the fast times that have leaked, which for such a short drill, can feel drastic.
The trainer also mentioned that basketball players usually have one foot that is stronger than the other. For example, if a prospect typically takes off from their right foot on their vertical leaps, their right leg will have more muscle. So if they’re able to push off the stronger foot and use all of their strength and body momentum in that direction for a shuttle run, their score will be better than if the light told them to go the direction of their “weaker” leg.
Combine (no pun intended) all of that with the aforementioned fact that prospects have had more time to prepare for the testing than ever before due to the elongated draft process, it makes far more sense why there are already so many historic numbers for the shuttle run this offseason.
