This is a shitty thread. Juan Diaz would get taken out on a stretcher. He probably couldn't beat a prime Livingstone Bramble.
even if rosario doesn't knock Diaz out, i think he still beats him. Rosario was no slouch on the inside, and he'd be the one timing Diaz, and in the very least, buzzing him repeatedly, and winning rounds.
Of course Chapo would be the big favorite to win, but he would have to be in the condition he was when he fought Camacho and Davis though, or he may get outhustled. What's with all these Juan Diaz threads, anyway? There are a lot more fighters out there.
