I’m gonna say Bud. He’ll take some punishment early, might even get knocked down. But I think his ring IQ and superior athleticism allow him to make the adjustments and from the mid rounds takes Cotto to school. Crawford vía convincing UD.
Even the drained Cotto that got khtfko against Pac would be the best opponent Crawford ever faced, i think in my mind. Even so, the styles favor Bud
I think Crawford would be stylistic nightmare for Cotto, but it would still be a very entertaining fight.
