Drafted vs. Undrafted NBA Players: comparing stats from the last 5 seasons

Comparing Drafted Versus Undrafted Players in the NBA

The NBA draft lasts two rounds each year, and only 60 players are selected (and we say "only" because this draft is dwarfed by the NFL's seven rounds and 256 selections and the MLB's 40 rounds and 1,204 selections). With 30 NBA teams selecting two picks each year, this means there may be a lot of players who wind up on a roster without being drafted.

We decided to take a look to see how undrafted players fare in the league when compared to their drafted counterparts. How far off are they, statistically, from their drafted peers? Do undrafted players actually pan out, and if so, how often? Let's dive in to find out.

Drafted vs. Undrafted: Head to Head

Average drafted vs undrafted nba player stats last five seasons

First, we looked at drafted players and undrafted players and compared them head to head over the last five NBA seasons. Drafted players outplayed those who went undrafted by quite a bit, with an average of around 50 games played, compared to an average of 32 by those undrafted. There was an even bigger divide when looking at games started per season – an average of almost 26 for drafted players, but only around eight for those who didn't get a call on draft day.

There was a similar separation when we looked at minutes played per game. Drafted players were on the court for an average of 21 minutes, while their undrafted counterparts played for an average of 14 minutes per game.

Next, we looked at an even more specific breakdown of stats between the two types of players per 36 minutes of playing time. Drafted players had better games than those who went undrafted across all categories, from points and assists to three-point percentages, blocks, and free throw percentages. The only category where they were equal was steals, with both drafted players and undrafted players averaging 1.1 steals per 36 minutes.

Positional Breakdown

We took a look at both types of players on a position-by-position basis. As far as games played, the biggest disparity was the shooting guard, where drafted players participated in over 50 games, while undrafted guys played in an average of 31. The disparity was less severe, however, across the board, with drafted players slightly getting more playing time.

While in most categories, drafted players had better stats than undrafted players, there were a few areas where the opposite was true. For example, undrafted centers had slightly higher field goal and two-point field goal percentages. Undrafted power forwards outperformed their rafted counterparts when it came to total rebounds and were nearly as efficient at draining threes.

Undrafted? No Problem

Here, we looked at undrafted players over the last five seasons to see whose star was the brightest. As for centers, Timofey Mozgov, who currently suits up for the Magic, performed the best across the board, followed by former 76er Shawn Long, and the Nets' Alan Williams.

Johnathan Motley gets top billing for power forwards, while Mirza Teletović, who currently plays for the Bucks, came in second for this position. His rebounds, though, were a bit behind the third player in the power forward category – JaMychal Green, who has played for the Memphis Grizzlies for the last several seasons.

The best performing undrafted point guard was Jeremy Lin, who is currently on Atlanta's squad. While his total rebounds are fewer than the third player on this list (Miloš Teodosić), he scored four more points per game than Teodosić.

As far as small forwards go, Kent Bazemore from Atlanta had the best stats of undrafted players, followed by Wesley Matthews of the Mavericks and Robert Covington of the Timberwolves. And Andre Ingram, who played for the Lakers during the 2017-18 season, had the most success as an undrafted shooting guard over the last five seasons.

How the Wins Stack Up

Finally, we looked at how undrafted players stacked up against a team's win percentage. How did the number of undrafted players affect a team's overall success? Our scatter plot illustrates teams that had a high number of undrafted players, such as the 76ers, tended to have a lower overall win percentage, while teams that featured a lower number of undrafted players enjoyed more overall team success, such as the Golden State Warriors.

We also looked at the overall percentage of undrafted players per team over the last five seasons. Philadelphia had the most at 57%, which means that over half of its players over the last five years have been undrafted, while the Oklahoma City Thunder featured the lowest percentage over the last five seasons of undrafted players at under 10%. Incidentally, the most successful team during that period was the Golden State Warriors, who had rosters that consisted of around 15% of undrafted players.

Wrapping Up

While teams can certainly find success with undrafted players, it does seem that those who are selected every June during the NBA draft do produce better stats and do help carry their teams to better overall seasons. When we adjust the stats per minutes played, they are pretty similar, but when you look at overall success in the NBA, teams that carry more undrafted players tend to lose more games.


We scraped for all NBA players of the past five seasons and collected stats, teams, and draft status. From there, the data were analyzed to compare drafted versus undrafted player contributions. We also gathered team records for the asset on win percentage versus the number of undrafted players. Stats were averaged to a per-minute basis to compare stats when both drafted and undrafted players were on the court. These stats were multiplied for the assets that include per 36 data. Players with multiple seasons during the last five years had their stats averaged. Advanced stats were collected but not included in the project. The player's team was calculated as the most recent team the player was a member of. The data included on may be incomplete or missing players and are not guaranteed to include every player. For the "Top Undrafted Players" asset, players with multiple positions over the last five seasons were included under the position they played most frequently.
