Vote for who you consider now to be at the complete top of their game and can absolutely have NO excuse if/when they lose now or very near future...
In other words, some one so in-form, you just cant see them losing.
I feel I took the question differently than most people, as I read it "who has reached the peak of their potential."
So with this reasoning I say Pacquiao and Marg and Calzaghe are as good now as well ever see them. Pavlik has good fights under his belt but is still in the early stages of his championship, Abraham just fought in America for the first time and is waiting for another big fight, and I'd like to see what Cotto does vs. Marg to see if he is done growing as a boxer.
Vanes Martirosyan
far from it but on the right track working with Ronnie Shields...
I actually voted for Cotto and Abraham... I can't see either losing in the next year or two.
Cotto is the best call. Pavlik I think is still pretty green and needs to improve his boxing, I could imagine quite a few boxers giving him trouble because of this.
I'm pretty sure Margarito is on the slide.
Abraham looks fine and shouldn't really be able to use age as an excuse but the way he relies on explosivity after long inactive periods is, I think, a young mans game and what is he 30?
Pacman's style too requires youth which is getting away from him now.
