In a way yes, but Khan never has had the power that Cotto has. Cotto was less durable at 40 but always found a way due to his power.
Good point, and Thurman many times capitalizes on fighters who are off balance by going to the side and throwing a heavy shot against his opponents momentum. If he can do that against Khan it's over imo.
Yea Cotto is definitely a far better fighter than Khan. I was just comparing them because they both react to getting hit horrendously and go all over the place.
