If you go undefeated in boxing does that make you the greatest boxer ever?

martinez can get in line, right now its pacquiao's turn to try to take away that 0. I guarantee if pac passes on the fight we will see floyd/martinez and I think floyd is a slight favorite in that fight as well.

Which one is the harder test in your opinion Martinez or Pacquiao? I think I'll go with Martinez just because he is in the bigger weight class. But Martinez can't play around too much against Floyd. I noticed Martinez likes leaving his hands low to invite his opponents in to counter them... Not what you want to do against someone like Floyd.

Calzaghe retired undefeated and I haven't heard one word about him being the greatest despite good scalps on his resume.

He wont be mentioned as one of the greatest despite since many believe he stayed in Europe too long before leaving to fight in America, but he'll sure go down as an HOF'er so that isnt bad
