WHO THEY
ACTUALLY FOUGHT

A record says how often a fighter won, not against whom. These ratings weigh every result by the opponent's strength at the time, then compare this fighter with the 99 rated fighters on the UFC welterweight roster (anyone with a UFC bout in the last two years or one booked).
