Again, though, the suggestion isn't to do anything she hasn't already done and compromise her style in a major way. Since she's not going to transform into an Andre Ward overnight, not quite having the skillset to be a complete outfighter doesn't mean she needed to stand in range too long looking to fire off calf kicks, leaving her head exposed. Since Weili can be tempted into moving forward and is hittable, just giving her that bit of room to do so and timing her on the way in looks to be a better gameplan than initiating contact and exchanging combinations with her dead in the middle. Not a radical idea and one that could still easily lead to defeat, but since Joanna came away from the fight with two heads but no belt, why not.
OK, my point is that to do that for a whole fight and not just flits is very, very difficult when you have someone whose footwork is faster than your own coupled with hand and leg speed that's evidently at least on par. Each action has to be thought through as it's not natural and instinctive to Joanna, and will, I believe, lead to openings during hesitation. As I said before, the pace and aggression of Zhang really cuts thinking time down to practically instinct and a number of exchanges where, imo, Joanna was stuck in the headlights and had to fight her way out of - I don't think she opted to do that, I think it was forced upon her.
Her style is not to go to war in fire fights; it's to pepper and pepper whilst slipping shots - I know she said she expected a war in there, but I bet even she was surprised at how many times they exchanged within microseconds of each other, essentially creating double hits that hurt her more than Zhang due to the power differential.
I just personally think you need a natural mover to keep someone like Zhang out for concerted periods of time, especially so if you're trying to give deterrents and something for her to think about in the meantime. Joanna showed an inlet with some of the front kicks, but for the main was comfortably outdone at range by Zhang's side kicks to the body, and also her work to the left leg, but worse from there is no right of reply from Joanna - at least by trying to hold ground she can strike back.
Should note also that Zhang literally caught Joanna's kicks (in her hands) at least 6 times in the fight, which added to Joanna's hesitancy as it was clear that wasn't a route to go down.
More interesting is that, when both were fresh, there was more figuring out range, and where Zhang was landing those side kicks before Joanna opted to close distance and not provide those opportunities. Zhang looked to have the advantage at distance.
I've watched the full fight 3 times now. I thought it was a draw watching live, but on each replay, I've got it 3-2 Zhang. Joanna's 3rd round was spectacular though, especially the inside crescent kick counter to the straight close to the end of the round.
Anyway, after all that, I think that the biggest issue Joanna has is not having enough power and the footspeed across the mat. They hit each other an almost equal amount of times, but the power really took a toll in the end. Joanna also said she had a head 'going on and off' which probably means she was feeling that power and it was distorting her. Also, she kept on that centre line more than she should trying to generate that extra power to match what was coming at her; I can see the logic behind it as clearly peppering Zhang is going to get you nowhere in terms of her respecting you enough to back off.
On a sidenote, how embarrassing is the hype to the fight straight after followed by the fight that it was? Jeez. "I wanna be the first man to stop him properly." "I wanna be the first man in the UFC to put him away." OK Israel.
