I think Rosa belongs vying for the main title too. Also think when Jade takes her first L, it's either gotta be for the title, or someone taking her title.
I would build Nyla as much as you can before the finals, Jade/Nyla and have Jade look like a beast beating a beast. (Ruby to finals works too though)
Then feed her jobbers on the Darks with occasional mid-card defenses on the main shows, while she gets more experience. Then do a big feud on the main shows if you gotta have her drop it down the line.
That would be a "AEW thinks the world of her" situation though, we will see just how big they are on her by the end of this tourney. I just don't want that 0 on her record to go without it being a big deal.
