Which career "0" was the most difficult accomplishment?

*This list can change at any time*

1) Floyd - Beaten top opposition since late 90's. He's ducked some fighters, but he has gone between 5 divisions and grabbed belts.
2) Calzaghe - 21 title defenses and grabbed a belt at LHW by beating Bhop. Only 2 division champ. Could have fought better fighters in their prime.
3) Rocky - Only undefeated HW Champ. Too few HW title defenses (6).
4) Lopez - 21 title defenses. Weak weight class.
5) Ottke - Gift decisions. By far the worst fighter on the list.

 

My vote is in direct opposition to other posters on this.

1. Ricardo Lopez. Guys in that weight class are washed up by 25. 28 is ancient, with most guys long since in the scrapheap. Deteriorating reflexes at the lighter weights are murder. Cleaned out the division for a long long time.

2. Rocky

3. Calzaghe. He was good to watch on his way up even before he won the title. He just has a style few people like very much.

4/5 pretty much a tie between Floyd and Sven.

Didn't Edwin Valero retire undefeated as a world champ?
All knockouts too, though no big names on his resume.
Pity his aggression got out of control.
