Lobo and Walter and a bit of Jessica were in an era when height and weight were used in the post.
Kelly Shoe not so bulky had a final great game before that few thought of her as a great post. Stef is an example alone with J MOORE of what CD can do with a tiny bit of talent and desire. Stewie is an example of an exception she had an exceptional body and exceptional abilities none others meet her characteristics.
A few other examples of rail-thin (more so than Olivia) successful posts in women's basketball at the WNBA level:
Jonquel Jones
A'ja Wilson
Dearica Hamby
DeWanna Bonner
Bonner (who I think is related to ONO somehow) is a particularly good example. She has now had a 9-year WNBA career for the Phoenix Mercury, and has been a WNBA all-star. The Mercury web site lists her as 6-4 and (get this)
143 pounds. She uses length, leaping ability, and agility to compensate for lack of bulk. I've watched her play against the Connecticut Sun, and she is as effective a rebounder as anyone in the WNBA.
Someone on the Boneyard said that Olivia's only asset is her height. That is ridiculous -- she also has leaping ability, very long arms even for her height, and more mobility than most posts. (Can you imagine Stef trying to run the floor with her?) She also has intelligence and the ability to soak up what Geno and CD are teaching, which she obviously is doing. I think Geno was right when he said that while Olivia will never be a banger in the paint, she can be a successful post on offense as well as defense by playing the same kind of game as those mentioned above.
Having said all that, it will not hurt (if she is going to play a similar game to Stewie even though she will obviously never be Stewie) for her to have a Tuck-like sidekick. I think Aaliyah Edwards could be that player. She has experience at the national-team level of basketball, similar to Kia Nurse, and for that reason I think she will be as ready as Kia was as a freshman to play high-level college basketball. I think it is more likely that Edwards will be in next year's starting lineup than that Paige will be, simply because there are other alternatives at the guard position but not for the role that Edwards can play.
