Everyone says Luka’s defense is bad, so I pulled the NBA.com tracking data (2025-26, 279 players with 1,000+ minutes) to see whether the numbers agree.
TL;DR: The eye test is mostly right. Luka covers the 2nd-least ground on defense in the NBA, faces the most rim shots of any guard, and is the most-isolated non-center, even though he rarely guards the other team’s best scorer.
Where the eye test is right:
- He barely moves. 1.63 km covered on defense per 36 minutes, 2nd least in the league (only KD covers less - he’s been in the league since 2007). A typical player covers 2.01 km.
- Teams get to the rim on him. 4.5 shots a game at the rim with Luka as the closest defender, the most of any guard (typical guard: 2.3). They make 72% of them, when 64% would be expected from those same shooters. For comparison: LeBron 64%, Edwards 62%, SGA 56%.
- Teams target him on purpose. He gets isolated 1.73 times a game (5th in the NBA, 1st Among non centers), even though only 10% of his defense is spent on the other team’s best scorer. Dort, Daniels and McDaniels each spend 25–30% on the best scorer and get isolated about half as often.
- It got worse over time. As a rookie he was the 30th slowest defender. and this season he’s 2nd.

*Typical = league median. Expected FG% = what those shooters usually make.
Where it’s not that simple:
- When teams isolate him, he allows 0.95 points per play, about league average. That stat only counts the attacker’s own shot, though. If Luka gets beaten and the ball is kicked out, the basket goes on someone else’s record.
- He’s legitimately good at a few things: 3rd among guards in defensive rebounding, 7th best at limiting threes (Again a lot of other factos included here), and among the best against pick-and-roll ball handlers (having a big body usually helps).
My take: smart hands, strong body, slow feet, and teams know it.
Curious what you think. Is there a stat I’m missing that would change the picture?
