How would the forum rate the power and general effectiveness of the following fighters: Lionel Butler - brutal knockout of Tony Tubbs, broke Bonecrusher Smith's jaw. Lamon Brewster considered him the hardest puncher he'd ever been in the ring with (sparring). Gary Mason - heavy thudding puncher, high KO ratio, well regarded by peers. Scored thunderous knockout over Tyrell Biggs, gave Lennox some problems. Travis Walker - not a hugely accomplished guy, but seemed to hurt or KD almost everyone he shared the ring with, including Arreola, Adamek, Pulev, and Browne. Supposedly knocked Vitali down in sparring also. Amir Mansour - very explosive puncher with a brutal one punch knockout of Fred Kassi. Also dropped the iron-chinned Breazeale and nearly stopped Steve Cunningham in a FOTY type candidate. Vids below.
