Several reasons AGAINST making this fight:
1. MOST IMPORTANTLY, Rose just won the title and has a queue of legit contenders to defend the belt against. I think she beats them all, but I need to see it. I really hate holding up divisions when there are actual contenders. Valentina on the other hand has completely cleared out her division. Yes theres Murphy, who will probably be about a +2000 underdog. Thats not a /UFC fight, thats an episode of bully beatdown.
2. Its not overly competitive. In striking range its actually super competitive i believe. But as soon as Val grabs a hold of her, Rose is going for a ride and the round is over. I could be wrong here, but I'd say Val is at least -500 favourite. To justify making a Champ vs Champ fight you need to have it be a close competitive fight, this is not that. Yes, Rose has a shot, but its not a good one.
3. Neither of them wants it. This is the same reason Val vs Amanda isn't happening, neither wants it. And why would they, they make no more money to fight a super tough person. If i'm Valentina, i'm just handing Lauren Murphy a beatdown for a million dollars and going back to Peru to third-wheel.
