This week's episode of WWE RAW saw the return of Shane McMahon who introduced the concept of RAW Underground. Seth Rollins recently revealed his honest opinion on the fight club during an interview with the Gorilla Position podcast.During the conversation, Rollins revealed that he is yet to finalise his verdict on RAW Underground. The Monday Night Messiah feels that this could end up being ridiculous in either a good way or a bad way. That said, he acknowledged the fact that it is a new concept that would be fresh for the audience. As far as his own take on Shane McMahon-led RAW Underground goes, he wants to be patient in seeing how things will turn out and what changes will be made. Here's what Seth Rollins had to say on RAW Underground, "Hey man, it’s outside the box. Our audience is different. They are begging for something different all the time, something new, something fresh. I think my verdict on it is TBD. Let’s see what happens. It could end up being ridiculous in a bad way or it could end up being ridiculous in a good way. Obviously the first week got people’s attention. We jumped up a little bit in our viewership which is great, I had no idea what to expect when I saw it on the sheet.""When I watched it back, I was not entirely offended by it, especially that it is a brand new idea in its infancy. Obviously they will make adjustments to it and figure it out along the way. I’m open to seeing what it becomes as time goes on." (H/T Wrestlingnews.co)Easy.
