Mayweather by decision either way, possibly stops him at lightweight, but I'd lean towards a decision... even at 154, the gulf in class is too big skill-wise for Pazienza to do much except present a willing target I'm thinking a 119-109 type of affair at LW... a little bt more competetive at 154, but still a pretty straightforward decision for Mayweather... none of the things Pazienza did well were the right things to trouble Floyd Mayweather
