I wouldn't be surprised if Zhang drops her. She has the clear the advantage in power and could arguably say she is the the more rounded fighter of the two. I just think people are forgetting how special Joanna is. She is one of the cleanest fighters I've seen in awhile from a pure technical stand point and she's a volume monster. When she gets going and starts landing those combos, she's tough to beat. It's similar to Holloway in that regard. At the end of the day, I just think Joanna will land heavy volume and out point her. It's going to be a really fun fight regardless, though.
