#1: Went on too long: The Undertaker
Don't get me wrong, I love The Undertaker. Who doesn't?
Debuting at the 1990 Survivor Series, the demon of Death Valley has been digging holes and claiming souls ever since, and has had a truly Hall of Fame career.
But there's no denying the truth: The Deadman is old.
In recent years, it has almost been painful to watch the legendary star compete, as he moves much slower than he did a decade ago.
Personally, I saw the WrestleMania 28 bout in Hell in a Cell against Triple H as the ultimate out, but hindsight is 20/20.
And with the Deadman reportedly setting up to feud with Elias, perhaps facing off against the next WWE show in Saudi Arabia, it looks like this career still isn't coming to an end just yet.
