It is quite possible that no top notch C type will enter the portal this year. We will find out pretty soon, but who would have thought a couple of years ago that Dorka and Cardosa would be available, you never know.
The one thing Uconn has as an advantage is that everyone thinks they will be absolutely loaded and deep at positions 1-4. So if you are a star 5, have already had a very successful career, and are looking for a greater challenge, like Lou or Dorka, Uconn with talent but no proven experience at the 5 is a perfect fit.
Suppose for example you are Lee at Kansas State, or Soares at Iowa State, or even Key at Tennessee. Your senior year is coming to a close and you had a season ending injury and could not enjoy it. You probably will have earned your degree and could face some interesting decisions.
If the season had gone as expected, you would have been looking forward to the WNBA draft and a new chapter in your life. But now you could declare, and be drafted, but the recovery time from serious knee injuries means you probably would not be available for play this spring, but importantly could be ready for the next collegiate season. So whether you got a redshirt year, or take the Covid year as a grad transfer, you could wait a year for the draft and show the scouts you had recovered, and maybe be part of a storybook season.
Now of course these players can also return to their current schools. But I don't think Kansas State will not be a serious contender, Iowa State loses Joens, and Tennessee loses their top two players and didn't get much from recruiting. So while those teams will be good, an experienced very good plug and play C added to the talent at the other positions would make Uconn the favorite next year, if they are not already.
I think for a player in that position, it could be an opportunity they would have to seriously consider. Obviously they may not take that route, and perhaps nobody that is an upgrade over a freshmen Ice or Jana will enter the portal, but beyond the unique circumstances of the players I mentioned, others might appear out of the blue that we never expected, like Dorka and Cardosa did in the same year. If not, I am confident the newcomers will be good, and by their junior or senior years they may be great as well, but there is a least a short list of potential additions that could be upgrades, if they decide to enter the portal, and we will have to wait and see.
