L. MacNaughton is a 31-year-old full-back at St. Louis City, rated 19.9 overall by Field Insider's model, ranking 359th of 436 on scout potential in the Major League Soccer. A seasoned veteran, he has been a rotation option this season (50.2% of available minutes). His defensive output reads 3.79 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on MacNaughton.
Judged on this season alone, MacNaughton graded 17 — a workmanlike campaign that ranks 45th of 54 of the 54 full-backs in the Major League Soccer, on 2 clean sheets and 3.793 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 6 → 17). Over the 5 seasons on record his form has trended upward, peaking in 2023/24.
On long-term talent our Rating reads 20, 46th of 54 of the 54 full-backs in the Major League Soccer. At 31 MacNaughton is into the veteran stage, where the age curve weighs on the projection, and a market index of 2.4 reflects that trajectory.
Past his 2023/24 peak — the recent trend is downward, so buyers are paying for what's left, not what was.

Strengths
- Attacking threat. Chips in from deep: 0.19 goal involvements per 90, useful for a full-back.
- Defensive volume. 3.79 tackles, blocks & interceptions per 90 — does the unseen work.
Watch points
- Game time. Only 50.2% of available minutes — needs a settled run to prove the level.
- Age curve. At 31, both level and resale value are on the downslope.
- Level. Rates below a nailed-on top-tier starter on our model.
Outlook
With a Rating of 19.9, MacNaughton carries the 46th-highest potential of the full-backs in the Major League Soccer of 54. Defensively he reads as solid defensive volume (3.79 tackles, blocks & interceptions per 90). Veteran phase — a short-term, lower-fee proposition as both level and value decline (0.9× and falling).
