At instances, Luka Doncic is a legal responsibility on the defensive finish. When he’s guarding away from the ball, he’s identified to lose focus and give up open pictures. He typically takes his time getting again on protection, giving freely simple transition alternatives.
However when he’s attacked in isolation, he’s a totally completely different defender. Within the 2023-24 NBA common season, he defended the fourth-most isolation possessions within the league and ranked within the 83rd percentile on these possessions, permitting simply 33.3% capturing.
Within the 2024 NBA playoffs, that success in isolation continued. He defended 18 extra isolation possessions than another participant and was within the 78th percentile. Doncic had notable defensive struggles within the NBA Finals, however these struggles didn’t prolong to one-on-one alternatives.
This isn’t only a Doncic story. His stunning success tracks with season-long information analyzed by SB Nation, which reveals that gamers most steadily focused in isolation protection typically carry out higher than the league common.
NBA groups generally hunt matchups, aiming to get their strongest offensive weapons remoted towards the opposite workforce’s weakest defenders. This technique is clear even to gamers simply coming into the league.
“The NBA is only a bunch of ball screens (and) switching,” mentioned Cody Williams, chosen tenth general by the Utah Jazz within the 2024 NBA draft, “getting their worst defender on their greatest scorer after which letting him go to work.”
“In case you can’t guard, groups are going to modify it on you, and also you’re going to should get a cease, or they’re going to maintain attacking you,” added Reed Sheppard, the Houston Rockets’ No. 3 general decide.
Nevertheless, the information suggests this strategy is likely to be flawed. There’s virtually no correlation between how typically a participant is focused in isolation protection — thus, how weak they’re perceived to be on that finish — and the way effectively they really carry out in these conditions.
The outcomes are comparable for different play sorts the place groups typically attempt to go after poor defenders, similar to pick-and-rolls and handoffs — elevating the query of whether or not the widespread follow of looking matchups is definitely an efficient offensive technique.
An enormous a part of in the present day’s sport
The primary quarter of the 2024 Jap Convention Finals highlighted this mismatch-hunting development.
“The Celtics simply proceed to focus on folks for the Indiana Pacers,” mentioned then-ESPN analyst J.J. Redick, now the pinnacle coach of the Los Angeles Lakers, throughout the broadcast of Sport 1. “They’ll create mismatches all around the court docket. They’re a heavy isolation workforce with nice creators.”
It began from the tip. On the Celtics’ first half-court possession of the sport, Jayson Tatum instantly went after Pacers level guard Tyrese Haliburton, who’s typically seen as a poor defender. Earlier within the play, Tatum introduced Haliburton’s man as much as display screen for him, necessitating a change. As soon as he was matched up towards Haliburton, Tatum cleared everybody else out of his means. The Celtics bought what they wished and let Tatum go to work.
A couple of possessions later, Jaylen Brown noticed Haliburton matched up with him and promptly backed him down. This compelled Pascal Siakam to go away his man and double workforce Brown, opening up a wide-open cross to Jrue Vacation, a 43% three-point shooter final season. In different phrases, as a result of Brown was in a position to get a mismatch towards a poor defender, Siakam felt he wanted to overcompensate defensively and thus gave his man a simple scoring alternative.
This sport of matchup cat-and-mouse is an on a regular basis prevalence within the NBA. Groups appear to be going after explicit defenders greater than ever. In pick-and-roll protection this common season, the 50 most steadily focused gamers defended a far larger frequency of possessions regardless of groups working basically the identical quantity of pick-and-roll as in earlier seasons.
And but these 50 most steadily focused gamers defended roughly the identical because the league common. So why are these “unhealthy” defenders persistently holding their very own?
The restrictions of focusing on defenders
1. Choosing the mistaken gamers
Maybe they’re not unhealthy defenders in any respect.
These 50 most hunted gamers within the pick-and-roll had a mean defensive ranking of 112.6 — three factors higher than the league common, based on Cleansing The Glass. The identical is true for isolation. If groups are attempting to go after the worst defenders most frequently, they appear to be doing a poor job of choosing their targets.
Some gamers really feel that groups may not be focusing on them due to their statistical defensive efficiency, however quite their look.
“It’s a stereotype that white guys are slower and fewer athletic,” mentioned Payton Sandfort, an Iowa star who participated within the 2024 draft mix earlier than in the end returning to highschool for an additional yr. “However quite a lot of us have been focused a lot that it has really helped us enhance our protection. We’re higher than quite a lot of different guys.”
Baylor Scheierman, picked No. 30 by the Boston Celtics in 2024, echoed the same sentiment.
“The notion is that when you’re white, you may’t defend as effectively and also you’re a simple goal.”
2. Defenses modify to assist their teammates
However even when the participant being focused actually is a poor defender, there are different components limiting the effectivity of matchup-hunting.
The obvious one is that the defender’s workforce additionally is aware of their limitations. As proven within the Tatum/Haliburton clip above, groups will typically work extremely onerous to forestall their weaker defenders from dealing with a one-on-one matchup with a robust scorer. The opposite gamers can sag off their man to assist, run to double workforce or simply typically be extra conscious on the weak aspect to help their struggling teammate.
It’s why rim protectors like Alex Sarr, picked No. 2 general by the Washington Wizards, are so vital within the fashionable NBA. He mentioned he would change his strategy if he noticed certainly one of his workforce’s weaker defenders remoted towards a star.
“I’d pay extra consideration to what’s happening,” Sarr mentioned. “Sag slightly bit extra off my man and attempt to assist out and get better as a lot as I can.”
The San Antonio Spurs’ No. 4 general decide, Stephon Fort, performed on a nationwide championship-winning UConn workforce final season that featured probably the greatest defenses in school basketball. He mentioned the Huskies would make comparable changes to help a focused teammate.
“It adjustments the way in which that we play assist protection,” Fort mentioned. “Our assist protection might be slightly bit stronger.”
A member of the NBA teaching group interviewed by SB Nation agreed with Fort, going as far as to say he can be prepared to “invite” focusing on at instances.
“In the event that they need to stall out and single out one particular person participant,” the coach mentioned, “we’re in all probability snug saying we’re going to construct a wall round that participant with our shift assist protection, perhaps pre-rotations.”
3. Limits offensive motion
This willingness to permit the opposition to go after a defender hints at one other limitation of the matchup-hunting offensive strategy — it disrupts the offense’s rhythm. Quite than working a standard offensive scheme — which entails ball and participant motion — the offensive gamers who aren’t isolating will typically stand in place and look ahead to the star participant to make his transfer. This offensive stagnation permits the protection to set itself and “load up” to the offensive participant.
Mo Dakhil, an NBA analyst for The Athletic, thinks looking matchups can result in environment friendly offense. However he believes groups generally spend an excessive amount of time making an attempt to get the matchup they need, abandoning the remainder of their offense.
“(NBA groups) get trapped into this mode of matchup-hunting,” Dakhil mentioned. “It actually hurts them and their offense, and it permits the remainder of the protection to relaxation.”
On this possession, Anthony Edwards tried to get the change onto Dereck Vigorous II, after which remoted on Derrick Jones Jr. as soon as Dallas rendered that technique unsuccessful. Whereas this occurred, the opposite Timberwolves gamers fully stalled out; they stopped shifting and watched Edwards dribble his means right into a troublesome fadeaway three. Discover, too, the rotations from Vigorous II, Doncic and Irving on the bottom, who knew they may help Jones Jr. on account of Minnesota’s lack of off-ball motion.
4. Focused gamers give further effort
Maybe the method of being focused elicits larger defensive effort and focus than a standard possession would. Gamers know when they’re being focused, and so they know what it means: that they’re perceived to be a nasty defender.
Cam Spencer, drafted No. 53 general by the Memphis Grizzlies in 2024, mentioned he takes it personally when he can inform he’s being focused defensively.
“That will get my aggressive nature going to say, ‘You’re not going to get by me,’” Spencer mentioned. “That fires me up much more.”
The identical seems to be true for Doncic. Right here’s an instance of Doncic on an off-ball possession within the fourth quarter of Sport 4 of the Western Convention Finals.
Doncic was clearly considerably unengaged on this defensive possession. He did some pointing and motioning, however his toes remained glued to the bottom. When the ball was kicked out to Karl-Anthony Cities, a wonderful three-point shooter who had simply knocked down an extended one on the earlier possession, Doncic made no effort to shut out.
Distinction that defensive possession with this one, the place Doncic was locked in instantly and appeared to take the Naz Reid matchup fairly significantly. When he’s defending on the ball — particularly when it’s clear the offensive participant thinks they’ve discovered a mismatch and is making an attempt to take advantage of it — he exerts far more vitality.
The exception: post-ups
However there may be one play sort the place focusing on does appear to internet important advantages: within the withering area of post-ups. The 50 gamers who defended the very best frequency of post-ups final common season gave up 104 factors per 100 possessions, effectively above the league common of 98.8.
One clarification for this distinction would possibly stem from the only of benefits: peak. The 50 gamers with the very best frequency of offensive post-ups have a mean peak of almost 6-foot-10. The 50 gamers who defended the very best frequency of post-ups measure a shade over 6-foot-6 on common.

“Bigs are attempting to attain within the paint, particularly in school,” Fort mentioned. “After they have a smaller man on them, I really feel prefer it’s extra environment friendly than an ISO, only a common ISO.”
Even a comparatively weak post-up participant like Rudy Gobert’s eyes mild up when being defended by a smaller participant like Doncic. The peak distinction, mixed with the proximity to the ring, generates a extra important benefit for the offensive participant than they might get in different isolation conditions.
Hunter or hunted
NBA offenses are extra environment friendly than ever — final season’s common offensive ranking was the very best in historical past. However one device within the arsenals of NBA offenses isn’t as environment friendly as groups appear to assume: focusing on defenders.
The 50 most focused gamers by frequency defended higher than the league common in isolation, and so they have been simply barely worse than the league common in pick-and-rolls and handoffs. The one play sort analyzed by SB Nation by which focusing on produced a transparent benefit was in post-ups, the place dimension variations come into play extra clearly.
Groups additionally appear to make false assumptions about which defenders are literally the weakest. Defenses have discovered methods to account for poor defenders with stronger rotations. When gamers can inform they’re being focused, it may possibly result in a rise in one of the vital essential elements of defensive success: effort.
However in the end, the inefficiency of focusing on is tied not solely to the protection, however to what it takes away from the offense. If groups are locking in on looking sure defenders, they’re doubtless abandoning the free-flowing offense that usually locations essentially the most stress on the opposition.
“If we’re continuously shifting the ball, we’re continuously having to place the protection in a tense state of affairs,” mentioned the aforementioned member of the NBA teaching group. “Everybody standing round, ready for somebody to assault (is) extra predictable and simpler to protect.”
There’s clearly a time and place for attacking weak defenders — each postseason, sure gamers are relegated to the bench as a result of they’ll’t guard in one-on-one conditions. However season-long information proves that groups are usually not correctly figuring out the defenders to focus on and have gotten overly reliant on looking matchups.
Or maybe they’re not looking in any respect. The defensive success of perceived liabilities like Doncic and different steadily focused gamers hints that groups making an attempt to reap the benefits of matchups generally turn into the hunted.
