I see the midfielders as the one attending the centre bounce and they are either inside or outside or can play both, wingmen are the one outside the centre square which was why those who mentioned Sloane should play on the wing and not be in our midfield setup anymore which he did quite well against Richmond before he did his ACL.In the olden days AFL footballers playing in the midfield were known as Rucks, Ruck-rovers, Rovers, Centremen and Wingmen.
