Awesome rhetorical question there boss!
I say INNOVATOR! Chael will end up doing SOMETHIN great....dude is talented beyond fighting.
You're right.
He made anderson Silva into a superstar. Silva really got elevated thanks to Sonnen selling the first fight with all the trash talking and nearly winning. Everyone was waiting for the rematch. In wrestling terms sonnen played the perfect heel character to put over Anderson and was working on getting wanderlei over until wanderlei lost the plot and instead turned Chael into a babyface.
He also stepped up to take fights on short notice and in the process elevated his own career as an analyst on FOX. Well spoken and smart like a fox when it came to creating opportunities for himself. I wouldnt be surprised if he became a promoter for the UFC down the road. White made statements that effect that he thought Chael would be the best replacement for him.
