Clean sheets

2.95 tackles, blocks & interceptions per 90 — moderate defensive volume, with 6 clean sheets across 36 appearances. Doing that for a lower-table side (17th of 24) 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.

Market valueRating

Solid = now · dashed = projected

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 (~9), then tapers with age. At 24, McKiernan sits on 9.4, at or near its peak. The blue line is McKiernan's projected Rating — 42.1 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.
