Team: Boston Celtics · Center · Age 24 · Contract: confirmed two-way · Base role: Maine lead big and contingent NBA fifth center
Conditional NBA projection card
| GP | Appearance MPG | 3PM | PTS | REB | AST | STL | BLK | FG% | FT% | TO |
|---|---|---|---|---|---|---|---|---|---|---|

Williams receives zero simultaneous minutes in Boston's healthy-roster 240-minute model. The card projects his line only in the 12 games in which he is activated and appears; those minutes substitute for absent standard-roster players rather than adding to 240.
Nine-category: not a redraft target, but blocks/assists are an unusual emergency-center combination. Points: the same contingent status keeps him on waivers. Dynasty: viable two-way stash in very deep leagues because a passing center who rebounds and blocks shots has multiple paths to a future backup role.
Why the line looks like this
Williams appeared in 22 NBA games as a rookie, including two starts, and averaged 1.4 points, 1.8 rebounds, 0.5 assists and 0.5 blocks in 6.6 minutes. Maine's official two-way announcement supplied the more informative development sample: 15.8 points, 10.9 rebounds, 4.9 assists and 1.8 blocks in 29.5 minutes across 28 G League games.
He then opened 2026 Summer League with 23 points, 13 rebounds and two blocks and remained a prominent interior defender. Those numbers support skill development, not an NBA rotation forecast. Queta, Robinson, Garza and first-round pick Cenac all hold standard roster spots, so Williams needs multiple absences or a transaction to reach fantasy volume.

Category shape
- Projectable strengths: rebounds, blocks and genuine passing for a center.
- Efficiency: likely positive FG%; FT touch remains a potential build constraint.
- Costs: no threes, uncertain scoring translation and turnover risk if playmaking expands.
- Build fit: dynasty taxi/two-way slot; emergency punt-FT center stream only after an activation.
Floor, base, ceiling
- Floor: spends the season in Maine and receives only end-of-game NBA possessions.
- Base: 12 NBA appearances at five appearance minutes, with most development outside the standard fantasy pool.
- Ceiling: two center injuries or a trade produce 15-18 minutes; his per-minute profile could support 5-6 points, 5 rebounds, 2 assists and one block, useful in deep formats.
Risk and confidence
| Component | Confidence | Reason |
|---|---|---|
| Roster | High | Officially re-signed to a two-way contract July 1 |
| Minutes | Very low | Four standard-contract centers are ahead |
| Rates | Medium-low | Strong G League sample, minimal NBA volume |
| Availability | Medium-high | No major current injury flag; activation eligibility drives games |
The positive reversal would be a standard-contract conversion or Boston moving a center. A healthy four-big room keeps him irrelevant to 2026-27 redraft regardless of Maine production.
Career record
Pre-NBA: Five college seasons — four at Drexel (2020-24; three-time CAA Defensive Player of the Year, two-time First-Team All-CAA, 186 career blocks) and one at Kentucky (2024-25: 10.9 PPG, 8.5 RPG, 3.2 APG, 56.1 FG% in 36 starts; his 115 assists were the most ever by a Kentucky 7-footer). College career: 141 games, 10.4 PPG, 7.4 RPG, 2.0 APG, 52.9 FG%, 62.8 FT%. Draft: 2025, Round 2, Pick 46 (Orlando Magic), draft-night trade to Boston.

Durability: 22 GP as a two-way rookie reflects activation limits and roster depth, not injury — no significant health flags on record. Trajectory: One NBA season of garbage-time minutes sits on top of a strong development record: elite college defense at Drexel, a legitimate high-major season at Kentucky, and a 15.8/10.9/4.9/1.8 G League line at Maine. In 2026-27 he competes for the Maine lead-big role and contingent fifth-center activations behind four standard-contract Boston centers. He becomes fantasy-relevant only if he earns a standard conversion or multiple Boston centers are injured or traded, unlocking 15+ minutes.

Open questions
- Does Boston use his two-way days for actual NBA development or preserve him as emergency depth?
- Can the 4.9 G League assists translate without an NBA spacing/shooting threat?
- Which center would Boston move or waive if Williams forces a standard conversion?
