Outlook

With a Rating of 28.4, O'Neill carries the 28th-highest potential of the defensive midfielders in the Major League Soccer of 40 — though on just 11 appearances this season, so the standing rests on a small sample. Defensively he reads as solid defensive volume (4.91 tackles, blocks & interceptions per 90). Experienced and reliable, but the value curve is easing (1.2× now → 0.9× projected in three years).

The blue line is O'Neill's projected Rating — 28.4 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.
