C. Wallem is a 26-year-old full-back at St. Louis City, rated 37.9 overall by Field Insider's model, ranking 248th of 790 in the Major League Soccer. In his prime years, he has been an ever-present this season (81.6% of available minutes). His defensive output reads 2.97 tackles, blocks and interceptions per 90. Below: strengths, watch-points, market-value outlook and the latest transfer news on Wallem.
Judged on this season alone, Wallem graded 23 — a solid campaign that ranks top 31% of the 135 full-backs in the Major League Soccer, on 5 clean sheets and 2.969 defensive actions per 90.
Year-on-year, that's a clear step up on last season (Season 18 → 23). Over the 4 seasons on record his form has drifted down, peaking in 2022/23.
On long-term talent our Rating reads 38, top 31% of the 135 full-backs in the Major League Soccer. At 26 Wallem is in his prime years, and a market index of 19.7 reflects that trajectory.
Past his 2022/23 peak — the recent trend is downward, so buyers are paying for what's left, not what was.
2.97 tackles, blocks & interceptions per 90 — moderate defensive volume, with 5 clean sheets across 32 appearances. Doing that for a relegation-threatened side (13th of 15) is harder than the bare numbers suggest: a back line under more pressure has to defend more often and protects fewer leads, so the volume — and any clean sheets — carry real weight. Going forward he chipped in 1 goal and 2 assists — a useful bonus from the back.
With a Rating of 37.9, Wallem carries the 41st-highest potential of the full-backs in the Major League Soccer (top 31%), and he is posting that for a relegation-threatened side (St. Louis City finished 13th of 15) — individual numbers are harder to earn on a struggling team, so his underlying level likely sits a touch above the ranking. Defensively he reads as moderate defensive volume (2.97 tackles, blocks & interceptions per 90). In the prime window — at or near peak market value, so the next two seasons are the ones to cash in or build around.

The gold line is market value — an index (not €) blending rating, age and league. It climbs through the early 20s, peaks around ages 23–27 (~20), then tapers with age. At 26, Wallem sits on 19.7, at or near its peak. The blue line is Wallem's projected Rating — 37.9 today — recomputed at each age, so it follows the same rise-and-fall as a career matures and declines. Solid = up to today; dashed = projected.
