Seth Rollins explains why The Undertaker was ‘terrifying’ backstage in WWE

Seth Rollins has recently made a move to Friday nights where he will become the SmackDown Saviour.
The Messiah has completely reinvented himself this year following the end of his babyface run at Hell in a Cell nearly exactly 12 months ago.
Fans panned Rollins as the champion and didn't see his challenger, The Fiend, as the heel Vince McMahon clearly did.
Rollins has been outspoken in his belief that WWE dropped the ball on that storyline and he had to go away and rebuild.
A man who was a staple of SmackDown for many years and also became an expert at reinventing himself is The Undertaker.
Survivor Series goes down next month and it will mark 30 years since the debut of The Deadman. It's reported that WWE will honour Undertaker at the event, but that doesn't include a match at this moment.
Undertaker retired earlier this year following his WrestleMania 36 match with AJ Styles but a man who never got a singles match with The Phenom is Seth Rollins.
Rollins did spend a lot of time with Undertaker, though and worked several tag matches with him, particularly in his Shield days.
Speaking on The Bump, Rollins explains how The Undertaker is just a scary man to be around!
"They've always been super awkward, mostly because he's terrifying," Rollins chuckled nervously. "I don't know if any of you have sat with him, but he's just a normal Southern boy, but he's still The Undertaker. To me, I'm not going to be that kid who dressed up as The  when I was four-years-old.
"To be able to have conversations with him, to be able to be in the ring with him, work with him, learn from him, is incredible. Anytime you get 30 years in one industry, you know, you're a master classman. Yeah, I wish I had fun experiences with 'Taker, but I've always been afraid of him."
In fairness to Rollins, Undertaker is a legitimately 6-foot-10 beast who is trained in MMA. That's not a man you want to mess with!
