One attribute Poch seems to like in many players is size - that's why Skipp was given a chance last season, as he's got the physique of a man although his muscles are not yet fully developed - and I think the same is true of Jack Clarke too. Of course both players are technically good but its their physique Poch likes which distinguishes them from Edwards, Sashoua and Markanday who are all small.
I'm not sure a Sporting Director needs to be 'over' the head coach, but even on the same level can 'challenge' the need for size. Its certainly true we need a squad with some bigger players in it, but imo some smaller players who have outstanding technique are needed too (not all big players do - look at someone like Loftus Cheek). Maybe one solution for this players would be going to the gym to develop legs like Modric - a slight player but amazingly strong legs and difficult to knock off the ball, but he became that way aged about age 23 after big clubs were not interested in him due to his slight physique aged 20. But that is the type of discussion that a Sporting Director can have.
