If Angel Reese actually wants to come to Storrs (which I greatly doubt) and if Geno is convinced that she will be a good teammate and citizen when she gets here (same as Evina and Dorka), then I'm sure he will be happy to have her. With her talent, she would make UConn a better team. But those are big questions ...
I think UConn's greater need is for a guard. People have been saying that UConn "only" has four guards for next year (presumably Azzi, Paige, Nika, and Caroline). I would count Caroline and Aubrey as wings rather than guards, which means UConn has only three "true" guards. I think that a fourth guard is needed more than a big. In this respect I agree with
@meyers7 , which is unusual in itself.
If a big of the quality of Reese is really interested, then of course Geno should and will take her provided the other questions are answered. But I doubt that anyone like that with an interest in UConn will be found in the transfer portal. I think UConn's front court roster for next year is adequate: Dorka, AE, two incoming freshman, and Amari/Piath.
