Really disappointed in Antonina's fight, not because she lost, but because she appears to have regressed badly and forgotten everything she's learned in the last 5 years. She didn't lower her base, get her hips away, or even fight grips when Chookagian got a hold of her, these are all things she's learned and showed that she can do in her previous UFC fights. And she was beyond passive on the ground, she was more active and defended a lot better against Roxy who's a better grappler than Chookagian. I don't know what went wrong, especially considering that she was training with Cejudo for part of their camp.
As for Dern vs. Cifers, yeah that was expected. That was a gimme fight for Dern if there ever was one, not sure if there's anything to be learned from it.
