Some of the podcasts I listen to suggest that

Lletget or Roldon will be the other midfielder with Morris on the right.

Sargent apparently still has a knock picked up in the Cuba game. If Sargent starts, I think it will be evidence that he is the clear #2. I'm betting that Gregg will start Zardes.

I keep hearing that Gregg is "gentle" with "his group" and that if you get a call, you'll probably at least dress. I heard that in relation to Wil Trapp who did not dress for Cuba. I fear that Zardes will get to play because of that concept. I also think that's why we will at least see Yedlin.

I didn't like Gregg from the first because of my tin-foil hat hatred of the USSF, MLS, SUM, Don Garber, Jay Berholter, etc. but the more I see of Gregg, the more I specifically do not like him or his management of this team.
