#3 The Undertaker could lend his pro wrestling expertise to WWE trainees in the Performance Center
The Undertaker is someone who has worked across generations in WWE, from the time when Hulk Hogan ruled the roost, to the Attitude Era, from the time that John Cena carried the company on his back, to the current era mixing it up with guys like 'The Phenomenal' AJ Styles.
The wealth of knowledge that The Undertaker has can be passed to the next generation in the WWE Performance Center, in much the same manner as Triple H and Shawn Michaels have been doing.
Pretty much anyone in the WWE Performance Center, who is following his/her dream of becoming a WWE Superstar has to be inspired by The Undertaker, who is arguably one of the biggest mainstays of the company for so many years now. And they would most likely be thrilled if a man who is a pop culture phenomenon coaches them to follow in his footsteps and become the draw and the sensation that he's been for so many years.
