The Camden Buzzsaw. He ground up opponents like a meat grinder. I put him in the swarmer category. He didn’t have one punch ko power but his opponents took a beating.
Dwight Muhammad Qwai had both styles, these styles enabled him to dethrone a well worn Mathew Saad Muhammad out of his WBC Light Heavyweight Title in 1981. His bout against James Scott at Rahway State Prison was a very good fight, won by Dwight, Qwai would not let a fighter breathe.
