Those who are in the know -- from Ronda Rousey herself to WWE -- continue to remain mum on the topic of the former UFC champion's rumored transition to pro wrestling. Even though it is WWE, of course, which is most responsible for teasing the possibility. 

Not surprisingly, current WWE superstar Charlotte Flair sees Rousey as an instant star who could drive big business for the company. But just how big are we talking? 

Flair, 32, has said for years that her dream since first following her father, two-time Hall of Famer Ric Flair, into the business was to one day headline WrestleMania. Is Rousey, 30, who hasn't competed in UFC since a 48-second knockout loss to bantamweight champion Amanda Nunes in December, potentially the perfect dance partner for Flair to get there? 

"Yes, she is. Yes. I mean, look at UFC, look what she did for UFC," Flair told CBS Sports this week during an appearance on Wednesday's upcoming "In This Corner" podcast. "I think if the story was told right and it was built, and this is something that WWE and Ronda agreed to, I think for sure it could be a main event at WrestleMania."

Throughout the 33-year history of WrestleMania, there has yet to be a women's match to headline the annual event. But not only did Rousey become an unlikely pay-per-view star for UFC throughout her dominant run as unbeaten 135-pound champion, UFC president Dana White has long credited Rousey for women ever being allowed to compete inside the Octagon in the first place. 

In the opinion of Flair, the idea of Rousey as a groundbreaker for female athletes goes beyond MMA and into the world of sports entertainment. While Flair and her fellow Four Horsewomen of NXT -- Bayley, Sasha Banks and Becky Lynch -- often receive credit for WWE's transition from the archaic Divas era to the current "revolution," Flair believes Rousey played just as big of an indirect role in women's wrestling being taken more seriously. 

"I think she opened the door for us on the main roster to main event shows, to be given major storylines," Flair said. 

Rousey's nickname of "Rowdy" was inspired by pro wrestling. The late Roddy Piper gave her his blessing to use it. But her MMA career never recovered from an upset 2015 loss to Holly Holm via knockout, which ended a 12-0 start (including nine via armbar submission) to the career of the U.S. Olympic medalist in judo. 

While she hasn't reclaimed the white-hot stardom she had at her peak, entertaining multiple offers in movies and television, Rousey has used the time away from the cage (outside of the disastrous return against Nunes) to rebuild her personal life after initially considering suicide. 

Last month, she married UFC heavyweight Travis Browne and now appears poised to follow her ex-MMA training partners -- also dubbed the Four Horsewomen -- into professional wrestling. While rumors that Rousey is currently training in Southern California haven't been confirmed, ex-teammate Jessamyn Duke is doing so, and Marina Shafir has appeared on the WWE Network as the real-life fiancee of NXT superstar Roderick Strong. 

The fourth member of the team, Shayna Baszler, has had the best success of them all, not just on the indie scene but recently making the finals of WWE's Mae Young Classic tournament. Rousey attended the tournament and was featured in videos produced by WWE, including what looked to be the start of an angle between dueling Four Horsewomen factions when Rousey and Flair confronted each other. 

Flair remains excited about the potential and what a feud with Rousey, if it comes to fruition, could do for her career. 

"My goal and my dream is to be an attraction for the company as a female," Flair said. "Having the opportunity with someone like Ronda, who I think opened the door for women, would not only show that I can be an attraction for the company but it would also show how far my talent surpasses working just other WWE superstars. 

"If I can take a star outside and just build this enormous match around our personas, nothing would mean more to have that opportunity with someone of Ronda's character." 

Although Rousey has yet to wrestle in an official match, she and her teammates are no stranger to making a splash within WWE. After being given VIP treatment at SummerSlam in 2014 and sitting in the first row, the foursome did so again at WrestleMania 31 the next year. Only this time, Rousey hurdled the ringside barrier and entered the ring to assist The Rock in a pre-planned confrontation opposite Triple H and Stephanie McMahon that instantly went viral.
