Castillo in his prime was all heart, the only guys to beat him were Machado and Montiel!

Having watched the Montiel fight, it did seem that his heart no longer allowed him to apply himself to fighting and although he appeared in fantastic physical condition, it was evident from the first bell that mentally, he was not prepared to fight.

Although from a boxing fans perspective I'm disappointed at his retirement, from another, more logical view, I respect him for alking away and hope he does not ned the sport again.
