Scouting notes, auto-generated — only stats deviating more than 25% from the division median make this list. No narratives, just deviations.
Who did they actually beat?
Full-career records re-graded by the tier of opposition — the same grading the Contender Series pick model uses. Records built on tier-4 competition are worth less than records built on killers.
