There is a video from UConn (apparently just released) which asks Geno to comment on the comparison between Aaliyah and Napheesa. He provides a full answer, saying that her intensity and her motor are just the same as Napheesa's, and she wants to have an impact on every possession. So in that respect he seemed to say that she is at the same level as Napheesa.
He said he wasn't so sure, at this point, that her game was as complete as Napheesa's. He didn't elaborate on what he meant by that, but I assume he is talking about position skills -- footwork, positioning, catching passes into the post. It is understandable that he would not be sure in October of a player's freshman year about the completeness of her skills in these areas, and it is pretty unlikely that Aaliyah is as skilled in these areas as Napheesa eventually became.
Geno also said that Pheesa played behind Stewie, Morgan, and Gabby as a freshman, and therefore had time to ease her way into her role, but Aaliyah will play a lot from the start of the season, so she will probably have a "baptism of fire". That sounds promising from the standpoint of her expected minutes.
Nothing was mentioned about fouls, but I have to think that Aaliyah is likely to get herself into foul trouble a lot until she learns how to play hard without fouling. Both Pheesa and Gabby were very foul-prone as freshmen and sophomores, but Aaliyah will probably follow the same path.
