This is not a thread to hate on Manny Pacquiao BTW, i have great respect for Pacquiao he has fantastic resume and i think he was a fantastic fighter. But with this recent thread of Pacquiao vs Mayweather that just popped up, i was looking back at Pacquiao's resume and did Pacquiao ever defeat a slick boxer ? I was thinking of a few fighters that might of been interesting style wise for Pacquiao, like Raheem after he destroyed Morales, Guzman when he was red hot, Casamayor is another one that might of been interesting.
By your definition of Slick does that mean when the Fighter get's on his back foot, run circles, lightly jabs when corned then clinches without any deductions, ducks below the waste leaves his arm out illegally & then evade? If So then yes he has faced plenty of them, in fact many of his opponent's after tasting his power ended up becoming very "Slick" on those very same nights, funny isn't it.
