It would do nothing for Hatton at all. I'm sure he would walk it but it really serves no purpose other than to go out with a win. But going out with a win is pretty pointless if you fight someone that 99.9% of people expect you to beat. It might make Hatton feel better for a while but when he looks back on his career it won't soothe the pain of the losses.

He should stay out.

Or fight Marquez.

But really should stay out.
