Well I could give several but I don't think you can give a better example than his first fight when Louis would corner him, sting him, and then Conn would come raging back to hurt Louis and fight him off.
Gatti.. With some guy you hurt them you should back off and set them up again. I never could stand seeing a guy hurt someone and swing for the fences leaving themselves open.
The great Aaron Pryor. He would literally throw himself at opponents when hurt. I recall him getting knocked down just to somersault back to his feet, right in the opponents face, the referee giving the standing 8 having to force Pryor backwards as he wants to fight right then and there. Pryor had a massive ego and was ultra competitive. Early in fights he liked to dance and showboat but if an opponent landed a strong shot (like the Dujuan Johnson fight), he cut all the joking and tried to overwhelm you.
Alexis Arguello. In the classic fight with Ganigan he was dropped. The cameras zoom in on his face. He was so pissed. Alexis goes straight to the center of the ring throwing massive straight rights backs Ganigan up. Next round he drops Ganigan and crushes him in the 5th.
