15 WWE Problems Only The Undertaker Would Understand

11. Never Realising His UFC Dream

From the get go in 1993, Mark Calaway was a huge UFC fan. At that point he was probably young enough and athletic enough to give MMA a shot. He may even have found some success in it, as he was genuinely a tough guy and MMA back then was easier to break into than it is nowadays. The thing was, back in the nineties, it simply would've been way too big of a paycut for Calaway to viably consider switching from pro wrestling to Mixed Martial Arts. It wasn't until 2006 that UFC really became successful. That's when it became big money and guys like Brock Lesnar suddenly had a new avenue to run down. But for The Undertaker, it was too late. He was already in his forties and physically worn down from years of wrestling. As he told Ariel Helwani in a 2011 interview, if it had been like it is now back in the day, he'd have definitely gave UFC a shot.
