His return is inevitable. A hometown fight against Corey, OSP or a returning Rumble for a rematch would be good. He would lose those fights and retire again of course.
No rumble, I think rumble is returning at hw and I think Gus gets melted again. I'd like to see him against Thiago Santos or even Dominick Reyes. Osp would be a good fight since Gus is coming off a loss and osp isn't at the tip top of the ladder like Santos and reyes
He needs a bit of a step back in competition to get his confidence back up. OSP makes sense. Perhaps one of the younger guys like Rakic/Walker/Krylov.
Rakić. Gus is still a big name, if he's serious about coming back he could get right in the mix if he beats one of the best prospects in the division. If Rakić wins, it would be a great boost for him after that BS decision vs Volkan.
