I was at the game and had a close-up look at both Dorka and Liv. I can tell you for sure that Liv has a noticeably more muscular build than Dorka at this point. That is why I expect Liv to be a more effective rebounder against top competition than Dorka.
If Liv goes up for a rebound against Aliyah Boston, I think she will have a 50% chance of coming down with it. I wouldn't give Dorka more than a 30% chance in the same situation.
This board has often complained about Liv's supposedly slight, beanpole physique. That was accurate when she was a freshman, but it has been quite inaccurate for a long time now. But the caricature does seem to apply to Dorka as of now.
Before the exhibition game, Geno commented about how Dorka's conditioning isn't yet where it needs to be. I thought he was talking about her stamina, but now I think that he was also talking about her upper body strength.
So I expect that Dorka will play if the perimeter shooters aren't hitting and the team needs inside scoring. But if the offense is OK and the priority is clearing the defensive boards, then I think Liv will get more minutes.
