Linemate and opposition quality
2025-26 · 5v5 · 1,082 min on ice · ranked against 270 defencemen · last season, until this season has enough games to rank
41st percentile · higher = stronger linemates
44th percentile · higher = tougher opponents
Middle-of-the-lineup deployment: average linemates and opposition.
Each value is the ice-time-weighted average season xGF% of the skaters Lohrei shared the 5v5 ice with. Small samples lean on each skater's previous season (or 50% for newcomers). Most skaters land between about 45% and 55% for QoT and 49% and 51% for QoC, so the percentile is the easier read.
