If Oscar could KO Mayorga, he sure can crush a former 108lb fighter who is going up 2 weight classes to fight him, and who is faaaar from a defensive wizard. Pac gets caught with good shots in all of his fights, and he was hurt against Marco and Marquez. Diaz connected Pac flush several times in their fight. Against Oscar, he`ll get hit harder than ever in his career. He`s going down. Not because Oscar is too good for him; It`s just that Pac is that small.
