Whatever she's doing in the PC is working! As I said, megastar!Jade was signed from AEW around Summerslam. She’s green as all hell so has spent a ton of time in the performance centre training. They’re playing the long game with her though.
Surely they do Mami vs Lynch. With Punk out that probably main events night 1.
I don't think the timing works for Mami vs Lynch. There'd need to be a big build for that considering Lynch just lost clean to Nia in a pretty huge match. I'm sure they (Becky and Rhea) could make it work well but I think it would feel forced.
I'd personally like to see Rhea in something with a bit more venom and aggression. There's possibly a good story with Liv or Nia but I don't think they have the star power to match Rhea. But whether she passes the torch or uses it to solidify her position, she needs a big story and feeling to go with the match.
