No doubt he is a KO puncher…he exploaded that one dude’s face and his eye was just hanging. But that video showed how a pro vs a joe can be. Mercer just has to hope he doesnt get caught. Like I said though Mercer is old and has lost a ton in his later years…but he is still a pro fighter so i think it may be interesting…if it stayes stand up Kimbo may have a shot if he lands a few good ones but Mercer is a former pro boxer so you never know.
