Both will duck for different reasons. Cotto because he knows he would be beaten down and have his career finished. Canelo because his handlers know he would be beaten down, and its too early in his career for that, for them to allow that to happen. Who the F wants GGG? Seriously having watched that performance against a very good opponent, who wants a piece of that? Unless they have some form of natural weight advantage...who is going to want that?
GGG has the power and the ability to give you a career ending loss. Most fighters with a heart who stick in there, will never be the same again as a fighter after fighting him. Lem will never be the same fighter again after that, if gets back in the saddle at a similar level he will start to lose the fights he would have won pre-GGG.
Lee is a warrior. I know that should he get past BJS he will man up and face GGG right away, regardless of the consequences. :good
