I know some posters have been brushing off the JJ chin concerns as non sense, but the bigger point there to me is that she is hittable.
vs Karolina: KK only landed 50 sig strikes, but 72% of those were to the head and she was stunned in round 4
vs Claudia 2: Claudia had 63 sig strikes landed with 90% to the head with a knockdown early on and an elbow that stunned her later
vs Valerie (the most interesting fight to me IMO): Valerie landed 103 sig strikes with ~70% to the head
I've always felt the way to beat JJ was to match her volume/output. Andrade is an interesting case here because of that exact reason...over 300 strikes against Hill and broke the 200 mark in a 2 rounder against Penne. Obviously JJ offers more of a threat than Andrade's previous SW opponents but she has the capacity to throw hard, and very often.
JJ is not elusive enough to prevent being hit the entire time. KK who is far below her striking level even managed to land 50 times on her. She WILL get hit and she is facing a style of fighter she hasn't encountered yet.
One more thing is if you look at Joanna's striking diversity, she is almost always in a 33/33/33 split (head/body/legs) against opponents that do not offer a primary takedown threat (i.e.: Claudia). Her leg kicks are vicious, but they also give Andrade a chance to swarm every time she opens up with one. I wouldn't be surprised if we saw Joanna either get tagged hard or end up off balance on some of those [naked] low kick attempts that she throws at times
as someone mentioned previously (and IMO), JJ's biggest threat are her elbows and front kicks down the pipe. I actually hope to see her open up with those beautiful teeps a bit more in this fight.
Regardless, Andrade is a legit threat no matter how simplistic her style may seem to some. High output and power is going to always be a potential problem against a fighter that accumulates damage and momentum over time and does not possess 1 shot KO power.
