Why is Erik Koch not on this list? he has won 12 out of thirteen fights most in the first round The only loss was to Mendes who laid on him for three rounds. Do you people actually watch these fighters and what skills they have.
@Doug, Because Erik Koch, as impressive as he has been, has not beaten any fighters ranked high enough to be ranked himself. Wins streaks don't make rankings. Beating notable competition does and Koch's most notable win is over Raphael Assuncao, who may have been ranked briefly once, but is far from it now.
