This isn't that complicated. We have a short three big rotation now. I would argue that two of the three have significantly under-performed expectations in Aaliyah and Dorka. Next year the most likely scenario is Liv leaves and Dorka stays and becomes the new starting center.
Do I worry that Dorka may be a step down from Liv? Yea I do based on this season so far, but I also believe she may be better particularly offensively as a C than as a PF. Regardless she is the obvious answer as to who the starting C is likely to be next year, and she is a true C, not a PF out of position.
The backup may or may not be a true C. Either Amari or Piath could be, time will tell, they both appear to have the ability to at least be an above average backup C, if not far more than that. Amari in particular may be a contender to start by her Junior year after Dorka leaves. They are C size, but because we will have several other talented PF types in Aaliyah, Ice and Ayanna for next year, if one of those three is outperforming Amari and Piath they could handle the backup C role.
So for next year I feel the pieces are already here or coming for our big rotation. We can start a true C in Dorka and might have a 6-5 substitute if they develop, if not a talented PF type say Ice who has the bulk to bang a little in the post.
Is it possible somebody is out there in the portal that could help us? Maybe, but not very likely. I also don't see it as an urgent need. If anything a backup 2/3 from the portal would be my first priority. Now if Dorka doesn't return things are different. In that case we might need someone like Ice to start as a freshmen or Amari or Piath would have to step up. They might be fine but it would be a major question mark.
As long as Dorka returns we have a known projected starter who should be pretty good, two good 6-5 prospects for backup duty, and several PF's that could at least be good backups at C if needed, even if they would be undersized against some.
