Other props I'm gonna stab really small:
Villante rd 2 at +575. His rd 1 prop pays crap, and Cummins could easily hit a TD and control Gian for a round, only to get clipped in rd 2 and finished.
Brazilian Cowboy KO +625. If he can stuff some TD's, LaFlare can be hit. BC will go balls out for the finish too.
Burgos dec +390. Pepey has 1, maybe 1.5 rounds worth of cardio. But he is tough, and even if (when) he gasses he could survive. Assuming he doesn't get put away early or pull off the upset of course.
