Predicting the next 4 WWE Hall Of Fame Headliners
2021 - The Undertaker
The Undertaker is one of the last remaining gigantic names that hasn't yet been inducted into WWE's Hall of Fame, and as mentioned in the intro, the company is running out of big names, which means that they might have to use "The Phenom" to get the fans excited about their annual ceremony.
At this point, it's quite clear that The Undertaker doesn't have much left in the tank, as he probably doesn't have more than a few more matches left in him. He's been teasing his retirement for quite some time now, most famously after his loss to Roman Reigns back at WrestleMania 33, but it might take him a few more years to truly leave the ring for good.
I wouldn't be surprised to see "The Deadman" be completely done with in-ring competition by 2021, which would open the door for a Hall of Fame induction.
