Speaking as a Red Bull fan, passing consistently out of pressure can be done, but it does take a team effort, and lot more time in training than the USMNT have in any given window. Any coach would have difficulty navigating the rotation of players, getting that pool to play as they should is difficult enough in a vacuum. The trouble is the instruction is most likely in direct competition with the club coaches who have the largest amount of training time with said player pool. The tactics Berhalter wants to employ run in contradiction to much of what those coaches want out the same players. That just doesn't seem like a recipe for success.
