I dont see a reason why they should let go of SWP and MKR for now. They need more women in the gym for scrimmages and it's not like they're blocking anyone's path to the A squad. Plus their experienced and leadership could be of great value for the newbies on the B-C-D group.
Foecke gained some grounds on Simone Lee this season and probably the next in line after the four vets. Lee put herself at a disadvantage by playing in Japan and not really getting the quality repetitions she needs in passing and receiving.
If they keep her around, Courtney to me is very intriguing. I think they'll switch her back to OH2 after the OG and when some of the vets retires. We have a great number of transitional players available but I think most of the "would be game changers" at least for the USA team are currently not in the gym.
