Given the current technology, Offsides should be determined by the part of the body that touches the ball first. If a player uses the foot, that’s the mark. If the player uses the shoulder measure from that. Then you get away from a head being offsides but the feet are on and the first touch was the foot (no offside advantage with the body part that actually mattered).
Offsides should be judged by foot position only, change my mind.
