My choice is John Cena. What is it about John Cena that makes him "the face of WWE"? You could say he's popular, but that only begs the question. In 5 years he's held the WWE title 9 times and more gifted wrestlers who are infinitely better on the mic take a second seat. His ring skills are severely limited and he is a pain to listen to on the mic. And yet he is pushed beyond anyone on the roster. I find him one of the most boring workers in the entire fed.
There are a number of workers more talented and charismatic than Cena to build around. Cena is favored because he appeals to little kids who get their parents to take them to matches and buy them merchanise.
2006 called, its wants it's thread back.
