#2 The Undertaker

It's true their match at Super Showdown was a complete disaster, but we can't let that write off the possibility of these two squaring off once again. Both Superstars are legends of the industry and capable of lacing up their boots for one more match against each other.
The Undertaker was reportedly furious after their match at Super Showdown. They had a shouting contest at gorilla position blaming each other for the failure of the match. The Deadman flew home in Brock Lesnar's private jet to avoid meeting with Goldberg again.

WWE should have Goldberg and the Undertaker make it up for their failed match at Super Showdown. But both Superstars are in their 50s and don't have enough gas left in the tank. It's up to the two Superstars to let bygones be bygones and get back into the ring once again.
