I fancy curry big for this one. mayweather hasnt proven himself enough as a welterweight curry late or points
Floyd's speed and quickness would give Curry problems but he would get figured out and iced by Curry of 147 in the mid rounds. Even at 154 during-pre Mccallum he should be favored heavily against Floyd. Curry beat a great technician in Starling twice and competed well early against another in Mccallum until he got broken down and ko'd. Floyd never fought a technician on their level. Floyd doesn't have that ko power to stop Curry which is another strike against him in this matchup. I actually rate Curry much higher than I do Floyd and consider Curry great, Floyd was/is good until he gets another big test as he's been very disappointing at 140 and over.
Curry would put the proverbial foot up Mayweather's ass for a surprising and spectactular three round kayo.
I like Curry to win. Not a fan of Floyd but he can fight and would give Curry all he could handle. I think it's a decision similar to the Starling fights from a score standpoint.
