The UFC / Dana White made the biggest mistake by letting Mousasi go to Bellator. Mousasi's notable wins: Update: Rory MacDonald (TKO) Hendo (TKO) Weidman (TKO) Vitor (TKO) Mark Hunt (Sub) Ovince St. Preux (UD) Uriah Hall (TKO) Jacare (KO) Gegard Mousasi is one of the true p4p best fighters in MMA: But perhaps the UFC let him go because they don't care to have a Dutch-Iranian MW champ. Having the Australian market with Whittaker is more profitable. Mousasi is a stylistic nightmare for Whittaker. He's a more well-rounded striker with better grappling. Only strong wrestlers like Romero can beat Mousasi.
