From what I've seen, I'd replace Brooks with Zimmerman and Acosta with Musah or Weah. Alternatively, I'd rather see Reyna at McKennie's spot, Aaronson starting on the right side (Weah backup) and McKennie in Acosta's spot.
Ultimately we need to find a way to get our best 11 on the pitch in a formation that works to their skills. I think Reyna is our best CM, much better in tight space than McKennie. We've got wingers to spare, and need him more in midfield.
To
@LIuconn's point, not sure how we start Acosta with this roster. I like him on the squad as a steady veteran player. A good sub for the more erratic McKennie if we are protecting a lead.
