From what's being reported, Murtough has total control of the football side of the club and will therefore be the head of football throughout the club.
The deputy DoF will work in tandem with Murtough to assist him in making sure all departments related to the football side are functioning to a optimal level. So from the scouting, data analytics, medical, sports science, education, recruitment, coaching, youth etc will be under John Murtough and his deputy.
Everyone on the football side of the club is under the authority of John Murtough right now. So Murtough along with his assistant will be in charge of making sure the people heading their respective departments on the football side of the club are hitting their targets.
Recruitment is something that most of us fans are most concerned about. So for us it's important to learn who will be heading the recruitment department because it'll be those people at the top of the chain in that particular department that John Murtough will have to rely on when making decisions on which players to bring in to the club. So I'm personally looking forward to seeing how the recruitment department will look after the departures of Bout and Lawlor.
But the direction on what to look for when recruiting players must come from the DoF/head coach. Then that will simplify things for the scouts and they can filter our a lot of unnecessary names.
