True, he knows the fundamentals of dumb inside and out... in fact he's been called the "Willie Pep of dumb" by several commentators (voices in my head). But D.T is so unorthodox with his dumb, I can really see him givng Ripcity major trouble.
When I look at Pacquiao fight, I'd definitely think he was on the juice. Same goes for Hurricane Hank, Sugar Ray Robinson and Marvelous Marvin Hagler.
