Daniel Cormier thinks Nate Diaz would be Jake Paul ’s biggest fight to date. Diaz officially became a free agent after the UFC waived his exclusive negotiating period Monday night. Paul wasted no time to call out Diaz after the news broke, and Cormier expects the fight to happen. Paul is coming off his biggest win yet last month, when he managed to drop and outlast former UFC middleweight champion Anderson Silva in an eight-round boxing match. But Cormier thinks fighting Diaz would be even bigger for Paul – especially from a sales standpoint. “I think Diaz is gonna fight Jake Paul,” Cormier said on his “DC & RC” ESPN show.
