Would have to go with Shane in this. UNless he actually was on the Balco back then, he was a beast at LW.
Haney would have shoved the **** out of Shane at the pre-fight face-off. Then he would've gotten knocked out a few days later.
It's called 'Body of work'. And the eye test. Shane was a fast, hard hitting combination boxer/puncher. You should have seen him back then.
His LW reign, Specifically his fights against Phillip Holiday, John Molina, Leija and Golden Johnson. He beat all of them up, he was too big, fast and physical. He was strong in the tie up and clench. Holiday was an undefeated champion, John John Molina was still very credible, Leija I'm pretty sure only had his losses to Oscar and Azumah. Shane pretty much out physical-ed everyone up until he jumped to WW. Shane doesn't lose to guys that are smaller framed than him other than Cotto (shorter but broader, so you could say he was really bigger) and Pac. Mayweather if you look was equal size across the shoulders. This was consistent throughout his entire career. I know those losses are WW fights but his style didn't really change. It's a stylistic foil I noticed about Shane through the years.
