In 2018, an unprecedented trade in MMA took place between the UFC and ONE Championship, but who won?
Former UFC flyweight champion Demetrious Johnson was traded for ex-ONE Championship title holder Ben Askren. Johnson went onto capture the ONE flyweight title, capping off his career by besting Adriano Moraes 2-1 in their rivalry.
Meanwhile, Askren came in with a bang by finishing Robbie Lawler in his octagon debut at UFC 235. Despite then being on the receiving end of the fastest knockout in UFC history courtesy of Jorge Masvidal, his ability to sell a fight made him a big star in such a short amount of time.
