Yes, they're both fast but Inoue is a more accurate puncher with more K.O percentage than Casimero.
I am eager to watch this match up to see what kind of Casimero to show up against the Monster after all these trash talking.
Donaire on the other hand still have his speed and a bit of power, one of his few weakness is the stamina. He tends to gas out and lose power during the late rounds. So, what do we expect from an old Donaire?
As we can see, Donaire might've lost against Inoue but sure he did some damage as well.
