collazo(i hate hatton, i thought collazo beat berto, but hatto clearly beat luis...), then malignaggi

Kostya Tszyu is obviously first... OBVIOUSLY.

Some prime candidates for the silver medal on his resume:

Luis Collazo - He's a damn good welterweight, but it was a very close fight.
Paulie Malignaggi - I'm watching the fight right now... Malignaggi is slick and has a tremendous jab, and Hatton crushed him. Very impressive.
Jose Luis Castillo - Lots of name value, but in my view, shot to death before the fight. The Reyes and Ngoudjo fights gave some evidence and his streak of losses against average fighters gives this theory credence as well.
Carlos Maussa - A champion who knocked out the highly regarded (at the time at least) Vivan Harris. Definitely a rumor that his win over Harris was a fluke and he was a one-hit wonder though.
Juan Urango - Very good fighter, still only one loss to this day. Made an example out of Ngoudjo recently to pick up a belt.

Vote in the poll... in my vote, I'm going to include margin of victory in my decision... Collazo might be the best fighter on the resume, but the way the fight looked makes it less impressive.

I voted Malignaggi.

hatton's 2nd biggest win is beating a shot JLC.
