I remember Nunn outboxing Marlon easily enough. Starling landed some right hands, but nothing to hurt Nunn. Floyd would be knocked out by Nunn.
Plus lets not pretend like mental midget SP Zab didnt give Floyd a tough fight. This is almost criminal. Floyd would literally go out just like Sumbu Kalambay.
At welterweight? I just want to be clear. Nunn was a great Middleweight and I'd favor him at 160, but a weight drained Nunn vs a fresh Mayweather at 147. I'll go with Mayweather clearly on points maby a mid or lat round stopage when Nunn runs out of gas.
Than if it is at middleweight I'd go with Nunn. At his best Nunn was great at 160. I think Mayweather is better pound for pound but he is not superman.
