There's no comparison between today's crop of fights and the incredible talent we saw back in the 80s.
Mancini would have torn through the lightweight class today given how literally and figuratively thin and fragile the current ranks of champions and contenders are. Vasquez, Abril and Crawford would have been overwhelmed by Boom Boom;s tigerish ferocity and his booming hooks. I don't see anyone remotely close to Alexis Arguello, not even an Edwin Rosario at 135 lbs. today.
