I don't really know. I could definitely see LDLT emerging as a depth option. I'm just not convinced there's an obvious injustice as of yet.
I'm probably being unclear. I am actually pretty fine with the roster as it is now qualifying having slept on it for a while. Time for exploring and experimenting has passed and Gregg should be relying on known quantities. Personally, I would rather not see Tim Ream ever play for the USMNT again and I don't really see what Roldan brings. That being said, we know what they are and what they're not. Just my 2 cents though:
1. Assuming we had extra roster spots to bring guys over, I would have liked to see guys who did not play over the summer, specifically Green and de la Torre*. Even if they do not play, just getting them in with the team to be evaluated by the coaching staff would have been nice.
2. While I am not enthusiastic about Ream, all of the other options I can think of are either potentially being moved (Richards) or just moved clubs (Miazga).
3. The quote does not really indicate that Gregg was happy about the decision or endorsed it. I'm just saying that if Gregg was unhappy with de la Torre's decision, I would be ok with Gregg omitting him. I get de la Torre's point of view, but I would say that Gregg calls in whoever he is most comfortable with, and the way to do get into Gregg's comfort zone is to suit up for the USMNT. I can't really speak to de la Torre's form as I have not seen him play, and I am sure Gregg has (good reviews though), but McKenzie can't get off the bench at Genk but he made the roster I imagine because he played decently well (errors included) in the Nations League.
The great thing is that this possibly the best collection of talent ever in a USMNT camp. It's cool that we can argue about fringe players, certainly a HUGE step up from where we have been. Hell I think we would agree that this collection can be even improved upon with the inclusion of different players.
*The positive side of these two being omitted to me is that it increases the likelihood of Reyna being moved inside. With Weah being out, adding one of these two to the roster likely would mean Reyna is still a winger which is where Gregg plays him anyways. I'd rather that not be the case, and I was simply mentioning it as an option.
