10. Chris Jericho
Fun fact- the Undertaker and Jericho have never (eeeeevvvveeerrrr- sorry couldn't resist) faced each other one-on-one on a PPV. Considering there are no other wrestlers with the amount of wrestling experience that these two possess, it seems inconceivable, but it is true. Furthermore, there are very few superstars that convey the same amount of respect from both the WWE universe and their peers as Undertaker and Jericho- not to mention their incredible abilities in the ring. So what better time to put these two together then on the grandest stage of them all? Both are entering the twilight of their careers and there is no doubt that this opportunity might not come up again. The story would be simple enough- a variant of the End of an Era story but slightly different. Jericho would play the globetrotting wrestler who learned all of his skills all around the world where he had to graft to make a name for himself. He would claim that he could beat the Dead Man simply because it would represent the pinnacle of his wrestling career- to defeat the biggest, most respected name in the wrestling world. Will it happen? I don't think there's any chance. Jericho is now putting over young talent, and the Undertaker is far from young. Furthermore, I don't think the WWE would think that any one would buy Jericho defeating the Dead Man. Still, it's a nice thought...
