Remember Rockin Rodney Moore the guy didnt have many KOs then went on a fantastic KO run of fellow contenders.

Also Herol Graham for a safety first guy , he stopped alot of fighters , just below world level.

Second to Nunn also showed great power when he starched Sambu Kalambay in 1.

Light punching Sven Ottka showed power when he KOED Tony Mundine.

Mike Sprott also not a big puncher 1 punch KOED Fraudley Harrison.
