Branch? No. Gastelum will probably get the title shot against the winner of Whittaker vs Romero so he's not an option. I'd put Weidman vs Souza or Rockhold as the next #1 contender's fight, even if they lost their last fight. Branch could either fight the winner of Brunson vs Carlos jr. or, if they really want to throw him in at the deep end again, the loser of the title fight. But Branch needs more than just one more victory to earn a title shot, he's only had one against a ranked opponent in the UFC so far.
