I will say that I remember some people thinking Ubaldo would be a one-year-wonder but I don't remember who (and that thread is long gone). His mechanics are definitely different now, but I think it's also in his head (I read an article about his grip and how it causes a blister and affected his mechanics when the blister was infected - kind of ridiculous, but who knows?).
Was a bad trade for both teams, Alex White and Drew Pomeranz haven't done s**t either, but at least they're controlled and could turn out to be decent.
And as long as we're bringing up old stuff, Zack Wheeler > Tyler Matzek and John Bowker blows
