That's because WWE had several Cena-level wrestlers during that time. Today it's a different story, he's all they got. The roster is extremely thin with super over stars.
This time last year they had a star who was bigger than Cena ever was, what did they do? Feed him to someone who doesn't even wrestle any more. Don't try them blame what they're doing on fan reactions. Hell I'd argue the "Cena sucks" chants don't contribute to him being over with. They just make him look bad, you can't even try and argue that it shows people watch to see him lose because he never fucking does. Bryan was more over when he was recieving "Yes!" chants from the entire crow and they've done their best to kill that.
Cena's not pushed because he's over, he's pushed because he appeals most to their current target market and that's exactly what's been killing their ratings.
