What am I looking at?
  • Individual refs: stats for one official across all Chelsea games they worked, even with different partners.
  • Ref crews: stats when the same one officials worked together on the Chelsea games (8+ games shown by default).
  • Team baseline: the Chelsea went 195-185 (51.3%) across this sample. Ref and crew win rates show how they compare to that team average.
  • Whistle differential: who gets called more. A positive number means opponents are whistled more often than the Chelsea.
