Usually it fucks a fighter up when they fight pissed off, ie Paul Smith when he fought David Banks on The Contender, Hatton when he fought Mayweather, etc.
But are there any fighters who are lethargic until they get a spark by something like that?
In Casamayor-Corrales III, whenever Casamayor got pissed off (by a low blow, headbutt, etc.) he really seemed to do some damn good work. His punches became extra-sharp and accurate.
I'm blanking for other fighters right now, but I'm sure all the knowledge on this forum won't let me down.
Examples?
Ray Austin talked shit and disrespected Wlad before their fight and Wlad said he would let his fists do the talking in the ring...they sure did.
I have never seen Wlad look so pissed off and angry come fight time...he had a nasty snarl on his face during the entrance, anthem and staredown...Austin was scared shitless...Wlad ended up knocking out Austin with ONE HAND in 2 rounds...Austin was Owned bigtime and we haven't heard a peep from him since that humuliating KO.
Mayorga too... good example!
Oscar against Chavez in the rematch for not showing him respect in the first fight. Oscar then went ahead and made an example of Mexican machismo Quit on his stool.
