I am not sure that Roach is that great and that if he is in your corner you are unbeatable

First Aaron don't go directly in. He moves increadible and to land any punch on him is a difficult task!
Manny has only streight forward offence. He does not have chin and deffence! He is beating all this non skilled guys because they play the same game and he is faster, but Aaron didn't play that game Aaron will make the same with Pac like he did it with Arguello, but faster because of the lack of deffence!
