Before 1990, Chavez/Taylor fight & the Tyson/Ruddock backlash... Richard Steele was considered amongst the best of all-time.
He made a mistake in the fight of the century, when Frazier floored Ali at the beginning of round 11, and Mercante called it a slip.
Smoger I haven't ever seen do anything annoying and he doesn't do premature stoppages. For the modern set he is the best.
