On Monday, LeBron James became the NBA’s only active 40-year-old and just the 32nd in league history. As a result, we thought:

Who is the best basketball player at any age right now?

We set out to find out exactly that. In keeping with the NFL’s summer countdown, we enlisted the help of NBA senior writer Tim Bontemps, draft expert Jonathan Givony and recruiting expert Paul Biancardi to name the best players ages 14 to 40. (Biancardi catered to the 14-16 age group, Givony went for 17-19 and Bontemps for 20-40.)

And while some age groups were easy to pick, other battles were extremely difficult: Jayson Tatum or Shai Gilgeous-Alexander? Jalen Brunson or Donovan Mitchell? Stephen Curry or Kevin Durant? Good luck with your decision.

Let’s get to the tips, starting with King James himself and ending with players in high school.

Not only is James the only 40-year-old in the NBA today, he remains one of the league’s elite talents. This season there are three players who are averaging at least 20 points, 7 rebounds and 7 assists per game: Nikola Jokic, Luka Doncic… and James. That he keeps company like that while merely setting the record for most minutes played in league history – and ranking in the top five in virtually every single statistical category – is proof that we’ll never see anything like it again become.
