Robinson and Sands played terrific. We still have these players playing in Europe:

John Brooks (Champions League team)
Mark McKenzie (on the Nations League Final team)
Matt Miazga (currently with Chelsea)
Erik Palmer-Brown (likely going to the Serie A)
Leonard Maloney (Borussia Dortmund)
Chris Richards (Bayern Munich)

We'll be fine, and that's not counting an injured Walker Zimmerman or Aaron Long.
