What arr the most viable options for both Bradley and Golovkin?

Neither of these guys are likely to get their dream fights. I don't see a Golovkin vs Martinez bout anytime soon, nor a fight with Cotto. Who would you like to see him fight? Maybe Barker or Sturm if it's possible? Andy Lee? Doubtful also that he moves up to 168.... In regards to Tim Bradley, I know he is awaiting Pac/Rios to challenge the winner. But, I wonder if he would challenge Rios should he pull the upset. As far as I know he hasn't made any mention of Provodnikov. And I see no reason for a Marquez rematch. So, what other interesting matchups do you think are viable for Bradley?
