10 Wrestling Careers We Wish Had Lasted Longer

10. Edge

Edge smashed through WWE's glass ceiling after cashing in his Money in the Bank briefcase on John Cena in 2006, marking the beginning of perhaps the most prolific five-year main event run in the history of the company. In fact, the Rated-R Superstar had held the world title on some 11 occasions by the time he called it a day in 2011 - that's more than two a year.

And yet, having retired at the age of just 37 - the result of a persistent neck injury - it felt like he had some unfinished business. Edge had at last become a face after returning from a lengthy lay-off a year earlier, opening up a fresh batch of opponents and character openings for him to explore (and somewhere down the road, perhaps, the possibility of a full time reunion with Christian).

But health considerations rightly took precedence, and he went out at the top, his farewell match a successful WrestleMania title defence against Alberto del Rio.
