John Cena recently spoke with Zap2It.com to explain why he took time away from WWE for FOX's American Grit:
"I've been a cornerstone of WWE programming since 2002. That's a long time, it's more than 10 years. So much so that a portion of our audience has direct complacency with me. 'Man, Cena holds everybody down. He doesn't give the new guys a chance.'
From a company perspective, as you know I hold it very near and dear to my heart, the dance floor is open, boys. I'm gone, let's see who steps up. And I like that. As much as I want to try to distance myself or as much as someone who views me would try to distance myself from WWE, I'm never going to go.
Personally, and this gives me a better perspective on Dwayne Johnson's path, you get to a certain point and you cannot attract any more fans. Essentially, my productivity from a company standpoint … I've done as much as I can — 15 world championships and a myriad of other accomplishments. I don't know what left I can do, but I still want to be able to put people in the building."
