I think he looked discouraged because he knows he can do better then he did. But he accepted defeat in a way and said he needs 1 or 2 fights to sand over the flaws he showed in the fight and then he'll be ready again. I like that mentality that he knows he still has more to learn as opposed to most fighters who feel the wheel is already built, Malignaggi knows that there's still more, and I like that mentality
