Personally I'm fine with the manager not being able to railroad through any signing they want. In recent times it always worked best with effective collaboration, providing it doesn't evolve into stupid compromises and different agendas under Rodgers and the committee.
Regardless of whether the head coach title is a long term, permanent move or not, there simply is not the a calibre of manager available who you could have complete confidence in after Klopp. In short FSGs efforts to reign back some of the power are sensible at this moment in time, but Hughes will have to prove himself as competent and as effective as Edwards to make the new structure work. Also, everyone is going to have to leave their ego at the door.
