I'll be honest. Waterson looked impressive vs KK as a very good fighter should. Aggressive and planting her feet for strikes all night. Always trying to hurt KK. KK is the type of fighter one can do that to as Grasso further confirmed. KK relied mostly on her athleticism and it's mostly shot. Not all girls peek at the same time and not all of them are on PEDs and even those who are can fall apart.
Joanna on the other hand is, as Zane from Bloody Elbow would say, a rote fighter. While fighting in a lower weight class means losing what athleticism she had from 5 years ago does greatly matter it's not the same as KK. We have seen JJ change styles nearly as many times as Overeem over her long fighting career. We might see it again in this fight depending if she has enough time to re-tool outside of ATT as she said she would but that remains to be seen.
Trying to look at this fight dispassionately I think the winner will come down to who is more dialed in and which gym can do best with what they got. Can JJ give JW and Michelle a new look or will she do the same as before and can JW and Michelle gameplan for it enough over the coming months to blow it out of the water as Rose did.
I don't know the gym politics around JW atm. I know JW and ATT do or did have an agreement to bring in fighters for each other's camps. I know Holly sparred with JJ.
IMO taking this fight while at ATT and if it goes to a close decision is just asking for trouble same as facing Weili or Tatiana and fighting to a decision. JJ will have to completely out class MW which is dubious at best as both of them are out fighters with MW also doing her in-and-out routine or finish her which is unlikely.
JJ is headlining so outside of dying she is going to make it to the fight. If she is compromised I expect MW to finish her. Outside of that this should go to a decision. If JJ can re-tool and blend in MT like she said maybe she can make it look good I dunno. Will see how it will play out.
I'm out for a bit. Enjoy the weekend. I'm going to miss most of it. 8(
