John Cena
John Cena has already been labeled by WWE as a future superstar. Just like the Rock and Brock Lesnar before him, Cena has all the tools to be a major star in this business, and everyone around him, including Cena himself, knows it.
At a young age, Cena has already shown that he has the talent to hold his own in the ring in terms of delivering quality matches and fitting the WWE style. And while he is currently struggling to find a character that is his own, something that will make him stand out and be unique, the diamond is under the rough. It took Steve Austin and the Rock time to find the right characters for them, and it will also take Cena time. Cena also has the all important look that is needed in pro-wrestling. Cena posses that special "it" that separates wrestling stars from superstars, it’s only a question of when it will happen.
The biggest thing that stands in Cena’s way is the possible problems that come with being pushed too fast. Often a push that comes too soon and too fast exposes a young talent’s inexperience and flaws, and thus sets them back years in development.
With WWE backing him all the way, being a home grown talent, and having all the tools that can and can’t be taught, Cena is headed straight for the top and should be one of the brightest stars in the business 5 years from now.
