I think Gatti scores a Tko late after a brutal fight. I wouldn't argue the opposite happening, either way I see a pretty brutal fight.
IMO I think this fight would have been better than a couple of those Ward episodes. The only way I see Gatti as the winner is stopping Paz on cuts. Vinny had the pressure to stop Gatti. Paz is actually one of the few fighters who had way more heart and guts than Gatti.
Paz is easily one of my fighters ever. Gatti is Gatti enough said. Epic war. Paz has under rated speed and power. I think Paz tko 11 or 12 is likely. Gatti could make it interesting but I can't see him stopping Vinny.
