I haven't read the whole thread here but, with as high as WWE is on Reigns I wouldn't be surprised if this doesn't lead to Reigns vs. Big Show. At some point Reigns has to be given a singles run and this may be the way to start it.
As they shouldn't, he hasn't earned it. He took a dump on the face of the best talent on the roster and said "fuck you, I don't have to do SHIT but show up and pin you after you carry the entire program". Disrespect begets disrespect. Undertaker is a selfish, arrogant, broken down old has been who can't give it up, who doesn't give one shit about the next generation of stars and helping the company that made him thrive. It's always all about him.
