Stian Gregersen, Rudy Camacho, and Zac McGraw lead the MLS 2026 Defender of the Year market with implied probabilities clustered tightly around 40%, reflecting trader consensus on their standout 2024 campaigns amid a deep field of center backs. Nashville's Gregersen dominated interceptions (league-high 2.5 per 90) and aerial duels while anchoring a playoff qualifier, Columbus' Camacho bolstered the Supporters' Shield-winning defense with minimal goals conceded and strong progressive passes, and St. Louis' breakout McGraw excelled in tackles won and clearances despite missing playoffs. Recent regular-season finales and playoff seeding highlighted these edges, but comparable stats from contenders like Jack Elliott and Robert Voloder keep the race competitive, underscoring MLS defensive depth and uncertainty over 2025-26 form, injuries, and team success.
