I don't think these lists mean anything much, but if you're going by anything it has to be primarily who the best fighters around are, surely? To say oh Mayweather isn't on there because he doesn't fight often enough but then have Tim Bradley is pretty laughable really, as if that would even be a fight, not to mention Bradley hasn't fought anyone great or been terribly active himself.. I'm only really confident on my top 3, which is telling as to the lack of fresh blood in this sport these days as Titofan pointed out. These lists looked a lot better not to long ago.

1. Mayweather
2. Pacquiao
3. Marquez
4. Agbeko
5. Martinez
6. Gamboa
7. Chad Dawson
8. Wlad Klitschko
9. Bute
10. Froch? Ward? Cotto? Khan? Hopkins? (felt he wouldn't have had many answers for Dawson and is on his last legs)

Like I say though, after the top few it really isn't an impressive list as it should be. You could change the order any which way and it wouldn't mean squat to me.
