You're forgetting RJJ. I thought Caltrashy beat Hopkins, it was close but a clear win for Caltrashy. The first fight with Taylor was a draw in my opinon, the rematch though was a close but clear win for Taylor.
The doubt over Calzaghe / Hopkins is nothing more than an internet meme. How anyone can say Hopkins won that fight after actually watching the thing is unfathomable to me.
Calzaghe and Kovalev will haunt bhop forever; nights on which the white man put their will onto him for all the world to see. Powerless to stop them, he was outsmarted by one (no surprise, really) and walked down by the other. Both stark reminders of what he is and where he belongs.
