Your thoughts on the comeback of Erik Morales?

I don't think he has any fighting left. He has nothing to prove anymore. I think he has hit his optimum in the jr.lightweights where he was able to unify the three world titles and inflict Manny Pacquiao his first decisive defeat in many years--in fact the Filipino's only defeat in the last almost ten years. Successive losses to Pacquiao, Barrera, Rahim and Diaz clearly demonstrated that he was already on the downside of a long career. With two losses in the lightweights, what makes Erik think that he can compete in the heavier, more competitive welterweight division?
