1. Brock Lesnar
He just retired, but already we want him to come back. It doesn’t matter if he’s “juiced to the gills”, there are plenty of people who would pay to see Lesnar come back for another run in the heavyweight division.
A rematch with Mark Hunt would be far more entertaining now, seeing as Hunt’s social media ramblings have become the stuff of legends. Lesnar brings a lot of eyeballs to the sport with his freakish (and synthetic) physique, and that would only be good for the UFC.
WME-IMG sure would love to have Lesnar back, as with Conor on sabbatical, Jones suspended, and Ronda retired they have lost many of the stars they thought they were getting when they bought the company.
