He still gets the largest crowd reactions and works the crowd the best during matches. Don't think the WWE somehow just overlooked that he beat Cena cleanly and nobody in the WWE can even come close to the reaction he gets during matches.
Just look at his match on RAW. Nobody came close to generating that type of loudness. The WWE is just keeping his underdog status for Wrestlemania so he wins it all. It's so predictable yet funny that even the WWE tricks the "smart marks" to think Bryan has been de-pushed or something. LOL.
Nobody in the WWE works the crowd during matches. Guys like Punk and Cena can get louder initial reactions but Bryan does the most important thing and creates the best matches.
