Guys who retired undefeated: Edson Pedro Nascimento (By the way, this is the right answer for anyone who retired undefeated with 30+ fights) Lester Jacobs Augustin Senin Samson Dutchboygym Jemal Hinton Michael Loewe Guys who ran up crazy long streaks before their first loss: Faruq Saleem LaMar Clark Brien Nielsen Guru Singh Marty Jakuboswki Yori Boy Campas (who is still worse than about 99% of the people the jackasses in this thread have listed) Anyone who says anything as stupid as Sven Ottke, Floyd Mayweather or Lucian Bute deserves to get kicked in the nuts, or at least have their ability to post on boxing websites revoked.
And Floyd was ducking the hell out of this guy when he was at lightweight (and it's not even Paul Spadafora - who it dumbfounds me that nobody has mentioned yet when people have had the nutsack to mention people like Ottke). http://boxrec.com/list_bouts.php?human_id=15692&cat=boxer Jacobs is clearly one of the best shout outs in this thread though.
ENGLUND, I thought JCC was a REAL ass-kicker. Man, you got all the way down to Mighty Mike. Are you an LA guy? Hell, I can pick quite a few if we're going down to club guys like MM. I know him well and he's a great guy, but def overated. I'm STILL not sold on Bradley but if he beats my boy, MP, then, I'll climb aboard the bandwagon. Actually, the only really decent fights I saw him in were Holt and Peterson. I STILL don't know how he beat LP, and would LOVE to see a rematch.
