You've been huffing too much glue if you think most people thought Hatton was going to beat PBF. Not too many people who are not rabid Hatton fans gave him too much of a chance.
Witter has the style to give Hatton trouble and maybe beat him. Everyone has seen what slick boxers (PBF and Collazo) have been able to do to Hatton, they both beat him IMO. I am a Hatton fan, but more of a casual fan, and I think Witter would give him a hell of a fight.
