An ex boxer...
Remember Cotto is not a natural welterweight and when a fighter moves up in weight classes (Like Cotto did) they usually don’t take their punching power with them. And personally I feel when a fighter moves up in weight classes it’s only because they lack the discipline that it takes to maintain their particular fighting weight.
I left a comment some time back about how Cotto works out with a plastic suit on and that’s a big NO NO in my book.
Now If Cottley comes to fight and he’s able to keep pressure on Cotto, then I see Cotto being stop for the second time in his career.
