I've said before and I'll say it again, the manager is the one that has to make the ultimate final decisions and hit submit.
I agree that where any of us would seek counsel is less of a priority(gpolin has his staff and discord, the competent USA managers have discord, offsite, BB-Mail that have all been utilized in the past). It is taking this information and being confident in the choices made because at the end of the day, tactics and roster aren't a poll and majority wins. We're voting for someone to make those decisions themselves because they're the one ultimately elected for the task.
Even in my time with Nippon U21, there were a couple of instances that I reached out to managers like A-Dub and EPK along with others. I took their advice on what I had available, but I never used what they suggested 100% because I had ideas that I wanted to execute while utilizing their advice. I would take that same approach to managing the USA U21.
I once had a team with 1757 players and was $25,835,360 in debt. This is not that team. Join the Discord group open to anyone, but especially for USA managers to improve your club or get involved with the U21 and NT programs
