USA fell behind because they committed, like, 16 turnovers in the first half. Clark definitely wasn't going to help them with that. Ogunbowale is a great player, but she absolutely would have been a poor fit: they already had three ball-dominant iso chuckers on the roster, and all three of them play better defense. And yeah, Reese definitely provides an inside presence, but she wouldn't have been any better than any of the players they already had in that role.
The backup guard they should have taken was Natasha Cloud.
