I am very interested in your views guys and gals.
Frank Bruno's punches used to blow away lesser opposition , with ease , so when he reached world class did his power become less affective due to the fact he wasn't a world class puncher ?

My theory is Bruno telegraphed his punches and lacked sharpness , which made his power less effective , someone like Tyson was all about speed and power combined.

Bruno at an early age blew British fighters away , but someone like prospect Tyson Fury , is a combination puncher. Frank could hit , but my question to you guys is how hard did he hit ?

Please give us your theories and compare Bruno's power to the following.
Please rank all of the following's power from 1 - 10 and put them in order.
Frazier.
Tyson.
Foreman.
Wlad.
Viltali.
Liston.
Lennox Lewis.
Frank Bruno.
Riddick Bowe.
Evander Holyfield.

Many thanks.
