#1 The Undertaker could be part of the creative team
The Undertaker wrestled in WWE for 30 years. He saw other wrestlers come and go. That experience in the ring and watching wrestling evolve is worth something. He saw top superstars such as The Rock and Stone Cold. He wrestled with Hulk Hogan in his prime. He wrestled Shawn Michaels and Triple H.
The Phenom has seen it all. In fact, he has seen everything that has worked and there are very few wrestlers with that same level of crowd control.
Too often, the creative team in WWE has not been able to book wrestlers consistently. Instead, they have chosen easy and repetitive storylines that have driven fans away from the product.
There are very few people that Vince McMahon would listen to. The Undertaker is one of them. The friendship between the two is well known.
The Phenom could help bring something new to the creative team and change the perception of the WWE product altogether. He can bring the changes that are needed to the main roster and make the show relevant once again.
