How was it short-lived? And what do you mean by hype? He came into the UFC in 2013 as a hyped prospect. Earned a title fight against the UFC's self-proclaimed GOAT in 2015. After that fight, from the end of '15- most of 2019 he went undefeated fighting in 2 weight classes and became a simultaneous champ in Bellator and Rizin. I'm starting to notice you go full retard a lot or are just clueless in general.
I guarantee you were one of the UFC only idiot fans that thought Roy Nelson was a great fighter. Probably picked him to win against the actual top fighters that he faced too when anyone with a clue knew he always looked like a punching bag.
