5 Teams that could answer The Viking Raiders' open challenge 

1) AOP

Seth Rollins and The AOP

Though they've already claimed the RAW Tag Team titles before, their run on the main roster hasn't exactly been the most memorable since splitting up with former manager Paul Ellering. Even with Drake Maverick, AOP could still use something else to give their bad-ass characters some recent credibility.

Now aligned with Seth Rollins, fans wouldn't put it past them to see this open challenge as an opportunity to reclaim the titles. Giving Seth Rollins the chance to weasel his way into a mid-card title opportunity would make them an all-champion faction. That would definitely be a sight to see.

This team answering the open challenge would make the most sense, more than any other team on this list and mainly because Seth Rollins' spotlight would rub off on them. More importantly, it would give AOP more watchable TV time than they've gotten since moving up to the main roster.

On top of that, AOP and The Viking Raiders could put on a 5-star match, giving the fans hope for RAW's Tag Team Division. Having big men that are entertaining used to be rare, but now there are people who prove otherwise, like NXT's Keith Lee. These 4 big men could do some damage in the ring. This match is literally neck and neck, so picking a winner beforehand is difficult to say the least. It's that mystery factor that would provide for second-to-none entertainment that may otherwise be used for a bathroom break.
