one of the most bad ass things ever. danny williams KTFO of that dude after dislocating his arm. f*cking balls.
abraham against miranda come to mind. any margarito fight. mayorga giving forrest a free shot at his chin. hopkins going up 2 to fight tarver. pac going up (17lbs) 3 division less than a year to fight dlh. pac giving cotto free body shot.
Winky when he gave Shane some free shots was pretty gangster but besides that he was a very good boxer but not badass
Tyson, Ali, Mayorga (and entertaining too!). The Mexican trio were all badasses as well (Morales, Barrera and JMM) I'd even put Margacheato in there if he wasn't such a cheating *******.
