I was cageside for the Holm destruction and it was intense. She kept getting hit hard and flush. Her chin was up and Holm was cracking it over and over again. The head kick finish was merciful in a way because she was taking a lot of real damage.
The right hands Nunes was landing tonight... it's like they should be dropping her but she just keeps getting drilled. She has some obvious problems and doesn't react well to getting lit up but I certainly don't think her chin is a weak link in the chain
Ronda may lack striking defense but her chin is pretty damn good. She took numerous shots flush from Nunes. Nunes starched Tate pretty badly too after a couple of strikes.
