Everyone says that you just need to take down Cyborg but doesn't seem to be all that easy. Kayla has 25 minutes to avoid getting knocked out and she won't be able to keep cyborg down once she gets her there either, she'll have to take her down multiple times. If Kayla had finishing ability against fighters of Cyborg's caliber that'd be different, but it seems highly unlikely that she is any serious threat to Cyborg on the ground other than trying to pin her.
You could say that we've never seen Cyborg fight someone like Kayla which is true (kind of, she has fought grapplers), but we HAVE seen someone like Cyborg fight Kayla and it didn't go well for Kayla last time. Not being able to finish Ladd and Ladd getting back to her feet isn't a great sign either imo. Cyber would beat Ladd in like one minute probably.
Cyborg is a easy to hit and likes to brawl. Now that she is older and going up against a younger fighter with knockout power it looks a lot riskier than plausibly getting rode out for 25 minutes.
