Hagler-Hearns.

Hagler had a nasty cut in the 1st round and still didn't give a fuk and kept on coming forward and throwing bombs. The Hitman for having great heart going toe to toe with 1 of the top 3 middleweights of all time. Not to mentioned he broke his right hand and still went at it with Hagler, even when he was knocked down and still try to beat the count.
