Mine is no doubt Arturo Gatti b/c everyone of his fights are amazing to watch.He is little but he has alot of HEART and these days you can't find a boxer like Gatti.Every fight he fights his butt off and he is determand to give 110% and put his life on the line.
He has a very tough fight againist Mayweather friday and I honestly have my doubts about him winning the fight but win or lose Gatti will forever be my favorite boxer.
