Cotto would destroy Hatton at 147 (unless it was in Manchester). Look, Hatton is great at 140, although I think Castillo will take him out. This fact remains though, Cotto is naturally bigger he is more comfortable at 147, I don't think Hatton can carry the extra weight well, although I doubt he will come back up ever so we will never know. The only reason for Hatton to move back up should be to give Collazo a rematch.
