I'd probably go for a Naz KO, in a competitive fight. P4P, for my money, Prince Naseem Hamed is one of the hardest hitters boxing has seen in the last 20 years. Seriously he hit like a hard hitting welterweight. Freakish , Freakish power. I just cannot imagine him not catching McGuigan and knocking him out. Barry McGuigan for me is a bit overrated as a fighter, I reckon he loses to most elite boxers.
