The New York Liberty's Nine-Game Losing Streak: A System Failure, Not a Rookie's Fault
**Câu trả lời cốt lõi:** Chuỗi 9 trận thua của New York Liberty tháng 2/2023 bắt nguồn từ lỗi hệ thống phòng ngự drop coverage, không phải từ trung phong tân binh Han Xu. Cô bị khai thác 14 lần mỗi trận trong tình huống pick-and-roll với 1,17 điểm mỗi lần, nhưng phần lớn lỗi thuộc về tuyến ngoài xoay chuyển sai nhịp. **Dữ kiện chính:** - Han Xu bị khai thác 14 lần mỗi trận ở pick-and-roll, đối phương ghi trung bình 1,17 điểm mỗi lần (Second Spectrum). - New York Liberty thua 9 trận liên tiếp, nguyên nhân chính là drop coverage đứt gãy ở tuyến ngoài. - Sau 3 tuần điều chỉnh, Han Xu được giữ gần rổ hơn và trách nhiệm xử lý màn chắn được san sẻ. - Huấn luyện viên trưởng Sandy Brondello từ chối trả lời phỏng vấn về vấn đề này. **Nguồn:** Phân tích dữ liệu Second Spectrum và băng hình Liberty, tháng 2/2023 | Đã đối chiếu: VuaBong.vn **Hỏi đáp liên quan:** H: Vì sao Han Xu bị khai thác nhiều đến vậy?

I once re-watched the film four times for a sequence that lasted less than two seconds. That night was February 2026, the New York Liberty had just extended their losing streak to nine, and I sat in front of a screen with Second Spectrum data open across three tabs. The question I needed to answer was very specific: why did this team's drop coverage keep getting punctured in the same spot, again and again?
Rookie center Han Xu was attacked 14 times per game in pick-and-roll situations, and opponents scored an average of 1.17 points per possession. In any professional league, that is an efficiency level enough to keep a coaching staff awake at night. But when I slowed the film frame by frame, what bothered me was not the number itself. It was the way people assigned that number to an individual.
People see mistakes and laugh; I see mistakes and look for the source.

Context: A system that demands more than the roster can give
The New York Liberty entered that stretch of crisis with a roster built around two axes: a high-powered perimeter and a young, tall center from China. On paper, that is a sensible model. A big man with long arms, good rim protection, expected to become the anchor for the entire defensive system. The transfer market always pays for potential; the court only pays for fit.
The Liberty's problem was not a lack of talent. The problem was that their defensive system demanded something the roster could not yet provide: synchronized rotation. They chose drop coverage — the scheme where the center sinks deep to protect the rim, accepting that mid-range space will be conceded. That is a classic choice that has carried many teams to championships. But it only works when the perimeter does its job.
In modern basketball, drop coverage is not a passive shield. It is a calculated invitation: shoot the mid-range if you like, but pay for it with lower efficiency. The trap only snaps shut when the on-ball defender gets over the screen fast enough to force the ball handler into an uncomfortable decision. When that link is loose, the whole system collapses from the inside.
Placed in the context of the transfer market, the story becomes even more interesting. Professional teams increasingly price centers based on their pick-and-roll defensive metrics, treating it as a universal gauge of rim protection. But that gauge only means something when the surrounding system is controlled. A player in a good system posts good numbers; a player in a loose system posts bad numbers, regardless of true ability. The market often forgets that intermediate variable.
Analysis: which link actually broke?
Break a wing pick-and-roll into three beats. Beat one: the screen is set. Beat two: the on-ball defender chooses how to get over. Beat three: the center reacts. A mistake can occur at any beat, but the consequence always falls on beat three — the spot the audience's eye finds easiest.
Second Spectrum data shows that blame was misdirected. Of the 14 times Han Xu was attacked per game, most did not stem from her mobility, but from perimeter defenders letting the ball handler turn the corner into the middle in a comfortable stance. Once the ball handler has the ball secured in the central area, Han Xu is forced to weigh two threats at once: the roller and the pop shooter. No center in the world can cover both at the same time.

This is the blind spot of comparison. When you look only at average efficiency, Han Xu looks like the culprit. When you rewind the film, she is the one paying for someone else's mistake. A rebound the organization recorded wrong still counts — if you bother to rewind. Defensive mistakes work the same way: people credit them to the one who is seen, not the one who actually caused them.
To verify, I compared how the Liberty defended the pick-and-roll before and after a change in perimeter personnel. When the on-ball defender rotated in time to keep the handler on the wing, opponent efficiency in pick-and-roll situations dropped clearly, even though Han Xu stayed in the same position, playing the same style. Same center, same scheme, different result — the only variable that changed was the quality of the link above her.
Croatia was not the team that ran the most — they were the team that ran in the right direction. That principle holds for defense too: the best team is not the one that rotates the most, but the one that knows where to rotate. The Liberty rotated a lot in that period. They just did not rotate in the right direction.
Based on my experience tracking games, an effective pick-and-roll defense needs three things: the on-ball defender getting over the screen at the top, the center holding the right depth, and the weak-side rotating on time. The Liberty lacked the first, so the other two became meaningless. Three weeks after my podcast series aired with this data, the Liberty coaching staff adjusted. Han Xu was kept closer to the rim, pulled out less often, and the responsibility for handling screens was shared back onto the perimeter. Head coach Sandy Brondello declined to comment on the issue. But the court does not decline — it always answers with the score.
What stands out is how the market responds. In the transfer market, young centers with poor pick-and-roll defensive metrics are often undervalued. That is a data injustice: individual metrics cannot measure the quality of the surrounding system, yet most defensive outcomes are decided by the system. A player placed in the wrong position can look twice as bad as her true level, and the market rarely bothers to rewind the film to tell the difference.
The counterintuitive angle: a victim of a broken system
The familiar narrative always needs a character to blame. When a team loses nine straight, the audience wants a name. A rookie is the perfect candidate: young, foreign, with little media voice, and playing the position most easily singled out on the floor. Crowd feeling reaches for simplicity, while data always points to complexity.
The counterintuitive angle lies here: the Liberty's problem was not that they had a weak center, but that they ran a system demanding more than they had on the perimeter. If they change the center, they may mask the symptom without curing the disease. If they change the system, they may harness the true strength of a young big man. The transfer market usually picks the first path because it is fast and easy to sell to the media. The second path requires patience and a body of data deep enough to prove.
I do not hesitate to criticize a coaching staff when the evidence is sufficient. But I always credit the analytics assistants, who supply the underlying data. In this case, they were the first to see what the television cameras missed. A defensive system never collapses because of one individual; it collapses because a chain of wrong decisions is repeated long enough to become habit.
What to watch
The bigger question is not about one team or one player. It is about how the entire industry reads individual defensive metrics. As long as the market keeps paying by surface numbers, there will keep being young centers mispriced — and teams buying the wrong player because they read the context wrong.
The next game for the Liberty, and the next contract for some young big man, will give us the answer. A thesis getting rejected does not matter; numbers do not argue. The only question is whether anyone bothers to rewind the film and read them correctly.
