Yan Xiaonan vs.
Mackenzie Dern
Two full careers, measured against each man's own division and against each other — the tape, the read, and every number behind them.
The men, measured.
Frame, age, layoff and recent form — green marks the edge on each line.
What the numbers say.
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.
