It's been confusing to see people praising UFC for being able to make stars while WWE can't, simply because it always seems to backfire harder for UFC than it ever did for WWE
Like yeah, Dwayne and Brock leaving hurt them bad when it happened, and they're still recovering from the pain of that (they don't trust anyone who legit gets into movies post-Dwayne and -Batista, and you even see that with them now, being hesitant to give the world title back to Cena since he's gotten his own show)
UFC got crushed focusing on Anderson Silva and only Anderson Silva when he finally lost, same happened with Ronda, and now Conor's about to make more (in money and attention) from one fight outside their sport than he ever made combined in there. They might be better at making stars, but they're also better at watching them fall and having no way to pick up the pieces quickly
