Maybe Figgy comes back with improved cardio and better wrestling, he's been with Cejudo and his team for a while now, I think they good in terms of gameplanning too. Previous Figgy was doing his own thing where he's king of the gym basically, the change could be great for him.
Personally I think Brandon is just in his groove at the moment and has a natural cardio that Figgy just isn't able to compete with, unless he's on the EPO now, which is possible.
It should be a case of Brandon having too high a pace, too much pressure, better grappling, more out put, fresher in the later rounds and so on, but Figgy has the power and physical gifts generally
Probably look into some props rather than play a side
