This thread is still superior to the "khan v valuev" thread. Khan will always be cautious after he got sparked by prescott. he will always try to fight at arms length in future. He could go afew rounds with the puerto rican.
Khan will win because the only way they would ever meet would be when Cotto was seriously declining after having to many wars. Right now Cotto in 5 In 4 years Khan by UD.
