Judah would probably have a few decent moments early on, but he can't keep up with Khan's work-rate, and at 33 i just don't see him having the hunger to hang in there when Khan puts it on him later on in the fight. I see Khan stopping him, but Judah has had success early on, in the past against top fighters, so it could be interesting.

He'd definitely be a credible opponent for Khan, and it would most likely sell.
