They have Seimone listed as a forward but she is very comfortable (not to mention capable) at the guard spot. She is very versatile but seems to be more of a 2 guard these days. Her handle, quickness and range on the perimeter are outstanding. Not to mention the fact that she and Whalen have logged significant minutes together as a backcourt combo with much success. Of the various combinations Geno will have at his disposal, he could easily run Sue & DT as the starting backcourt and then sub in Whalen and Seimone. Team USA really has excellent 4 guards in this lineup, which is plenty IMO.
If the past is any guide--even more so since Griner is now unavailable--the committee will go for more size on the inside. Which is why I would go with Asjha.
