I think DC deserves the shot over Gus. Even though Gus should get his rematch eventually, I feel that he could take another fight in the meantime because Manuwa, while a good win, is not a great win. DC has been winning for a long ass time and finally getting top 10 win in Hendo is what he needed to get into the title picture. I say DC vs Jones first, with Gus taking a fight in the interim and then getting a shot at the winner.
But Gus vs Jones will probably happen first and DC will be the one taking another fight.
