I don't see this as a mismatch at all. I think Quintana is a very good fighter. And this is something of a crossroads fight for him. He already lost to one of the top welterweights in Cotto. A similar lost to Williams will pretty much end his days as a championship fighter. His back and career are kind of against the wall. I expect him to come out fighting. I'm still debating this fight but I would not be shocked if Quintana came out on top
