I loved the choice of McCallum, he is imo the greatest 154 lber in boxing history. I'll nominate Virgil Hill. Edit: someone beat me to it. :good I'll add Dariusz Michalczewski.
Everybody loves Hearns..I mean no matter what style you like..You liked Hearns..Floyd is respected but not liked. But james toney for sure..You guys just seem to forgot what he did..Man Toney was exciting..
Michael Spinks gets remembered too much for lasting 91 seconds against Mike Tyson, and not for being an ATG, and arguably the best fighter of the 80s. He was not only one of the greatest light-heavyweights of all-time, but also the linear HW champion, and an extremely versatile and adaptable fighter.
Terrible Terry Norris & Ricardo El Finto Lopez are two the come to mind. Especially Lopez probably the most underrated fighter of the last 25 years.
