My prediction: Geno is at most a game or two away from replacing Anna with Aaliyah in the starting lineup. I think his postgame comments (in the floor interview with the TV announcers) strongly implied this. ("To advance in March, you need a strong inside presence -- offensive rebounding, defensive rebounding -- and she provides that.")
I see the Asjha Jones analogy more than the Tina Charles analogy, but a more recent exemplar for Aaliyah is Morgan Tuck. Morgan was also a star in her freshman year, before she re-injured her knee. Morgan had the same strength in the paint and rebounding ability, with the flair to hit the occasional jump shot from further away. Morgan also knew how to position herself without the ball to get a pass and finish without opposition. I see all those things in Aaliyah.
The biggest question with Aaliyah is how many minutes she can play before she gets into foul trouble. Can she learn to control her fouling without losing her aggressiveness?
If you want to find someone to compare to Tina Charles, I suggest that you consider Mir McLean. Mir isn't as tall, but she has the same rock solid body and the same competitiveness in the paint. She also has the same immaturity as a freshman that Tina also had of going on "space walks" and missing assignments, i.e., not consistently having her head in the game when she isn't battling for a ball in the paint. It will take a year or more for her to outgrow that, and then her physical skills (strength, speed, and athleticism) appear to be comparable to Tina's.
As I said elsewhere, I think both Olivia and Evina will remain in the starting lineup all year, and before long their statistical production will justify that. Evina's stats other than scoring have been exemplary in the first two games, as Olivia's was tonight. Olivia really just had a "bad 4 minutes" at the beginning of the 3rd quarter of Saturday's game during which she shot 0-for-7; otherwise her productivity offers little to complain about. Her running the floor and getting transition opportunities has been superb in both games.
