Cotto, IMO is far from overrated. What has he done wrong? You can see vast improvements in his technique every fight.
He is undefeated, Who is there left at 140 that would have made you believe he is not overrated? I am very impressed with him, it's not just his power, it's also his intellegence in the ring, his timing and his movement. So I guess the question is, if he is overrated, who do you rate higher at 140?
