5 WWE Superstars who got better with age

#2 13-time WWE Champion John Cena

From the moment he set foot in OVW, John Cena's trainers were convinced that he was destined for stardom in WWE. He floundered for a little while on the main roster but soon found his footing as The Doctor of Thuganomics. Cena then enjoyed a meteoric rise to the top, winning the WWE Championship from JBL at WrestleMania 21.

But as he was being given his monster push, the West Newbury native wasn't the most polished in-ring performer. His matches didn't live up to expectations and the hardcore fans started to turn on him. During a feud with Kurt Angle in 2006, Cena was even subjected to "You can't wrestle!" chants.

Over the years, he developed into a much better worker and even had a five-star match with CM Punk at Money in the Bank 2011. However, his best stretch of in-ring performances came in 2015 when he would defend the United States Championship in an open challenge each week. He had incredible bouts with the likes of Kevin Owens, Dean Ambrose, and Cesaro.
