I remember the last time "Lightning" met "Thunder" and it wasn't pretty. I think this fight will be a lot more competitive than that one, but Floyd will still win, maybe by late stoppage.
I like Hatton, but I don't think he brings too much more to the table than Castillo or De La Hoya did. The fight in, in part, hinges on if the ref allows Hatton to use his mauling style against Floyd.
