WWE decided early this year to strap the rocket to Roman Reigns' back and make him the next big star of the company, the flag bearer for the promotion. That meant booking him to win the Royal Rumble and, presumably, having him go on to defeat Brock Lesnar for the WWE world heavyweight championship at WrestleMania 31.
As you know, that's not what happened.
He won the Royal Rumble, but the fans in Philadelphia that night made him pay for it, showering him with boos. This even with an endorsement from The Rock. It was bad enough that WWE seemingly changed plans and had Seth Rollins cash in his Money in the Bank briefcase to win the title at WrestleMania, pinning Reigns (who wasn't even champion).
Now, in an interview with Live Audio Wrestling, Reigns says that entire ordeal actually greatly helped his career:
"In sports entertainment, professional wrestling, entertainment, storytelling, you can do anything, you can tell any story you want to. It's difficult to say, especially within what we do, with hindsight. I think there is a lot of things we could have done or maybe thought about, but it is what it is, it really is. It all happened for a reason. Bryan and myself were both hurt we were both coming back around similar times. 100% it didn't help me coming back around the same time as Bryan, especially with everything he has gone though over the past year, year-and-a-half. People talk about getting through adversity and going through some tough stuff, the stuff that happened to Bryan, the ups and downs, I think everyone was rooting for him (Bryan), I was rooting for him. I still to this day root for him. I want to see Bryan back in a wrestling ring, tearing the house down with myself and all the rest of the boys.
"It was just a tough situation, regardless of what happened or how we could have changed that night as far as responses, as far as having the crowd react properly to me, or how we wanted them to, it didn't. But it helped me, it helped me grow, it left a huge impression on me, you know I thank Philly every day for that. You have to learn fast in this business and I'd like to think I'm doing that, but without that night, that was a huge kick in the ass, that lit a fire under me. If you've seen what I've done in the past six-months, I think you can tell Royal Rumble definitely helped me."
