Is Cena the next Hogan?
Let's look at how they're similar...
1. They're both really popular with the kids
2. They both have great physiques
3. They're both terrible wrestlers
4. They both have decent mike skills (Hogan is better, obviously, but Cena still has time to develop)
5. They're both been given long title reigns due to their popularity with the kids
6. Because of their popularity with the kids, they both help the WWE sell a lot of swag
The only real difference I see between the two is that Cena is often booed by the "hardcore" wrestling fans and Hogan is often universally cheered. From that prospective I say that if Hogan arrived during Cena's time he would get the same reaction. Hogan was fortunate to be a wrestler during the 80s when the whole "smart wrestling fans" concept didn't really exist, so the idea of booing someone for lack of wrestling talent wasn't prevalent during that time.
Like it or not (and I don't, honestly), I think Cena may be the face and the future of the WWE.
