good question.. in boxing its ALL about the heart. and to me the first person that comes to mind is the great ARTURO GATTI..
he had a heart of a lion. no matter if his eyes swelled up sooo bad he couldnt see.. or he broke his hands in the middle of the 6th round in a championship fight. or he got dropped 5 times.. he always BEILEVED in his heart he could win.. and in some of his fights ive seen him all damage up but still pulled off a miracle KNOCKOUT!
i salute you ARTURO GATTI.. you never give up and never stop swinging.. heart of a TRUE CHAMPION!
