I would put Wlad K in there too. Sorry. Citron is scary too. I saw him destroy a guy. But for me Cotto and Pavlik really stick out. They bath have a jaw line that can cut stone and when they knock you out you think the words retirement before you think the words rematch. I can see why Floyd hasn't opened his mouth too much about Cotto. I think deep down Floyd respects him and could possibly fear him. I mean Jesus look at the guy.
