Jaylin Williams — Two-Way Profile (3 Seasons)
Source: BBall Index (bball-index.com) — written with the Basketball Analytics Expert Sage active.
The Question
The framing question for Jaylin Williams: a 23-year-old backup big has gone from 13 minutes per game (23-24) to nearly 20 (25-26) on a contender. What's actually moving in the data that's earned him those minutes, and what's the role he can sustainably hold inside OKC's bigs rotation now that Chet (at the 4) and Hart (at the 5) anchor the front line? Two sub-questions worth keeping separate. (1) On the defensive side: is the impact reading a real breakout or sample-size noise on a backup-big role? (2) On the offensive side: does the stretch + connector profile do enough to keep the offense from leaking when he's on the floor with the second unit?
The 25-26 sample (1,277 min) is the largest of his career, which is itself a signal — and the cleanest evidence we have of what the player actually is.
Part 1: The Big Picture
LEBRON at 1.59 in 25-26 is roughly equal to last year's 1.61, but the read is very different — the per-possession impact has held steady while the minutes have climbed by 18% (16.68 → 19.65 MPG) and the LEBRON WAR has jumped from 2.00 to 3.24. He is doing more total work at the same per-possession quality, which is the cleanest version of "earned minutes" you can ask for.
The split tells the actual story. D-LEBRON at 2.41 is a three-year high and a major jump (0.93 → 1.33 → 2.41). For a backup big, a defensive impact reading at 2.41 is in the same neighborhood as Hartenstein's 2.29 — top-tier among NBA frontcourts. That's the breakout. Meanwhile O-LEBRON at -0.83 has dipped from 0.27 last year — the offensive layer is the soft side of the trade-off, and the question for the analysis is how much of that is a real cost vs. role-context noise.
Offensive Talent at -0.56 is below the league-average baseline but actually an improvement on his 23-24 reading of -1.35 — he's net-negative on offensive talent across all three years, but the gap has narrowed. Usage Rate at 15.6% is appropriately low for a complementary big. He is not asked to do much on offense; the question is whether what he is asked to do leaks the unit's possessions.
| Metric | 2023-24 | 2024-25 | 2025-26 | Read |
|---|
| LEBRON | 0.48 | 1.61 | 1.59 | Held two-year level on more minutes |
| O-LEBRON | -0.46 | 0.27 | -0.83 | Soft offensive layer this year |
| D-LEBRON | 0.93 | 1.33 | 2.41 | Defensive breakout — three-year high |
| LEBRON WAR | 1.65 | 2.00 | 3.24 | More total work at same per-possession impact |
| Offensive Talent | -1.35 | -0.69 | -0.56 | Below-baseline but climbing |
| Minutes Per Game | 13.0 | 16.7 | 19.7 | Role expansion year-over-year |
| Usage Rate | 13.5% | 14.6% | 15.6% | Complementary-big band |
Part 2: The Offense
Stretch shooting — the load-bearing skill
The offensive job is to space the floor and make the secondary read, and the data says he is doing the spacing job at a real level. 3PT % at 38.28% sits inside a stable three-year band (36.81 → 39.87 → 38.28). Stable FG3% is even more pinned (36.93 → 37.50 → 37.17) — his 3PT prior is firmly ~37%, with no percentage story to tell beyond "he is a real shooter and the model agrees."
The volume part is the more interesting movement. 3PT FGA Per 75 at 7.22 is the highest of his three years (5.90 → 7.01 → 7.22), and 3PT Attempt Rate at 72.73% is also a high — almost three out of every four shots he takes are threes. That's a floor-spacer archetype done at high volume; he isn't a center who occasionally launches, he's a perimeter-first big whose offensive role is essentially "make the C&S three." C&S 3PT Shooting Talent at 1.03 (climbing each year from 0.32 → 0.92 → 1.03) confirms the talent layer matches the volume — the catch-and-shoot specifically is where the value lives.
The 3PT shape itself is consistent with the role: 3PT Shot Making at 0.08 is positive but modest (which fits — he is converting at his prior, not above it on harder looks), and the composite 3PT Shooting Talent is at the soft end of his band. The right framing: he is a steady ~37% shooter at high volume, not an elite execution upgrade. That's enough to keep the spacing real.
| Metric | 2023-24 | 2024-25 | 2025-26 | Read |
|---|
| 3PT % | 36.8% | 39.9% | 38.3% | Inside ~37-38% band |
| Stable FG3% | 36.9% | 37.5% | 37.2% | Prior fixed at ~37% — no percentage story |
| 3PT FGA Per 75 | 5.90 | 7.01 | 7.22 | Three-year high — real volume |
| 3PT Attempt Rate | 63.2% | 69.2% | 72.7% | Floor-spacer archetype confirmed |
| C&S 3PT Shooting Talent | 0.32 | 0.92 | 1.03 | Climbing each year — talent matches volume |
| 3PT Shot Making | -0.12 | 0.23 | 0.08 | Modest-positive — converts at prior, not above |
Finishing and creation — the soft layer
The non-shooting offensive picture is more constrained. Finishing Talent at -1.00 is the worst of his three years and consistent with the archetype — he is not a rim threat. Rim FG% at 61.7% is below average for a big (and below his own 64% prior). Box Creation at 3.64 is positive but down from last year's 4.34 — he's contributing as a connector, not as a primary creator. Playmaking Talent and Passing Creation Quality read in the high band (top quartile or better among bigs by these readings), which is the connector value.
On-Ball Gravity is in the high band (climbing each year), which is a genuinely surprising read for a backup big — defenses are paying him meaningful attention with the ball in his hands, presumably from the DHO and high-post hub actions OKC runs through him in second-unit groups. Off-Ball Gravity at the 71st percentile and rising is the spacing payoff — defenses are treating him as a real shooter and staying attached.
| Metric | 2023-24 | 2024-25 | 2025-26 | Read |
|---|
| Finishing Talent | -0.94 | -0.94 | -1.00 | Not a rim threat — fits archetype |
| Rim FG% | 63.3% | 64.1% | 61.7% | Below-average for a big |
| Box Creation | 2.88 | 4.34 | 3.64 | Connector contribution, not primary |
Part 3: The Defense — The Breakout
Help defense + post defense — the engine
The defensive impact reading is the cleanest story in his profile, and the components support the headline. Help Defense Talent at 2.14 is essentially elite for any defender, let alone a backup big (band 1.44 → 2.66 → 2.14 — last year's 2.66 was the peak on a smaller sample, this year's 2.14 is on 1,277 min and is the multi-year-confirmable read). Help Defensive Activity at 2.00 is the volume layer saying the same thing — he's rotating, contesting, and recovering at high frequency, not occasionally.
Post Defense at 1.29 (recovered from a 0.53 dip in 24-25 on small sample) is positive — he can hold up against post-up bigs in spot minutes, which matters for the fit question (when Hart isn't on the floor and Jaylin slides to the 5, the post-defense reading is what you need to be functional). Rim Protection at 0.99 is positive and a three-year high (0.77 → 0.71 → 0.99) — solid rim presence even if it's not the elite-tier reading Hart and Chet post.
Defensive Positional Versatility at 65.58 is a three-year high, meaning he can credibly defend across 3, 4, and 5 — broader than a typical backup center, which is what makes him fit alongside both Hart and Chet without exposing the lineup defensively. Blocks Per 75 and Steals Per 75 are inside their bands (no meaningful stocks story) — the impact is in the help and rim layers, not the takeaway layer.
| Metric | 2023-24 | 2024-25 | 2025-26 | Read |
|---|
| D-LEBRON | 0.93 | 1.33 | 2.41 | Three-year high — the breakout |
| Help Defense Talent | 1.44 | 2.66 | 2.14 | Multi-year-confirmable elite reading |
| Help Defensive Activity | 1.81 | 2.20 | 2.00 | Sustained high volume |
| Post Defense | 1.15 | 0.53 | 1.29 | Recovered — useful for spot 5 minutes |
| Rim Protection | 0.77 | 0.71 | 0.99 | Three-year high |
| Defensive Positional Versatility | 60.4 | 62.1 | 65.6 | Three-year high — guards 3-5 |
| Defensive Role Versatility | 52.9 | 55.1 | 46.3 | Slight narrowing |
| Blocks Per 75 | 1.10 | 1.34 | 1.18 | Inside band |
| Steals Per 75 | 1.15 | 1.01 | 0.87 | Inside band |
Ball screen navigation — the absorbed weakness
Ball Screen Navigation at -0.85 is below average and mostly stable (-0.92 → -1.13 → -0.85). Like Hart, he is a drop-coverage big in pick-and-roll situations, not a switchable one. The 25-26 reading is his best of three years but still negative — the trait says he can be hunted in PnR by a good guard with a real screen.
Matchup Difficulty at -0.61 means his matchups are below league-average difficulty — the OKC scheme is choosing his assignments, generally putting him on bigs whose offensive profile he can credibly defend rather than asking him to take the opponent's lead creator.
| Metric | 2023-24 | 2024-25 | 2025-26 | Read |
|---|
| Ball Screen Navigation | -0.92 | -1.13 | -0.85 | Drop big — can be hunted in PnR |
| Matchup Difficulty | 0.26 | -1.23 | -0.61 | Easier matchups by scheme choice |
Part 4: Team Fit — Strengths and Absorptions
What OKC gets
A switchable-enough backup big with a stable ~37% 3PT shot on real volume (7.22 3PT FGA Per 75) and an elite-tier help-defense reading. The combination is rare for the role: he provides the spacing the second unit needs to stay competitive offensively, and the D-LEBRON of 2.41 confirms he isn't giving any of that back on defense. Defensive Positional Versatility at 65.58 (the highest of his three years) means he can play next to either Hart (with him at the 4) or Chet (with him at the 5), without forcing a coverage hole — which is the fit attribute that makes him a real part of the bigs rotation rather than a third-string body.
The connector role is the secondary value. C&S 3PT Shooting Talent climbing each year + the high-band passing readings + Off-Ball Gravity at 71st-percentile-and-rising say the offense doesn't stagnate when he's on the floor — defenses respect him as a shooter and the ball moves through him as a high-post option. For a player with a -0.56 Offensive Talent reading, that's the right shape: don't ask him to score, ask him to space and connect.
What OKC absorbs
Two things, in order of how much they constrain. First, the rim-finishing limit: Finishing Talent at -1.00 and Rim FG% at 61.7% mean possessions where he's the finisher are negative-EV. OKC has to keep his touches centered on the perimeter shot and the connector pass, not on rim attacks. In small-ball lineups where he's the only big, that constraint can become a coverage hole the offense has to design around.
Second, the pick-and-roll vulnerability that Ball Screen Navigation at -0.85 reflects. Same trait Hart carries — fine in drop coverage with strong perimeter containment, exposed when the perimeter wall thins. In bench groups where neither Cason Wallace nor Dort is on the floor with him, the math gets harder. The role expansion to ~20 minutes per game has to happen in lineups where the perimeter coverage is still credible.
Third, the small-sample caveat on the headline impact. 1,277 minutes is a meaningful sample but not quite a "this is who he is permanently" sample for a big who's just earned the role. The 24-25 reading of D-LEBRON 1.33 (on 784 min) was the prior; the 25-26 reading of 2.41 is the current data; the truth is probably somewhere in the middle, weighted toward the larger 25-26 sample.
The two-way verdict
The 25-26 readings make the case for what Jaylin Williams has become: a backup big who fits the OKC bigs rotation in a way that wasn't obvious from his earlier seasons. The defensive breakout is real and on enough minutes to take seriously; the offensive shape is the right one for the role (high-volume C&S three, no rim creation expected, connector passing); the fit is structural — he can play next to Hart or Chet without forcing a coverage hole. The absorbed costs are real but match what a backup at this price should look like. Forward-looking, he is the bigs depth piece OKC's two-big design needed, with room for the playoff role to expand if the defensive impact reading holds on the larger sample.
