From The Athletic:
"The Nationals did not mention that many of the players responsible for the title would also be looking at their rings for the first time remotely. That fact has irked some in the organization, sources told The Athletic, particularly players, as they were both excluded from the decision to proceed remotely and unaware that it wouldn’t involve the entire team opening their rings at once."https://theathletic.com/1827117/2020/05/20/inside-a-confusing-nationals-ring-ceremony
On Saturday the Nats will have "a small number" of players open their rings while the rest watch on a Zoom meeting. On Sunday the team will show the video on line. Some of the guys who didn't get selected to be among the first to get their rings sent the email from the FO over to the Athletic.
So who are the chosen few? I'm going to guess Scherzer, Strasburg, Zimmerman, Turner, and Doolittle.
