Offsides can be determined by sensor technology: Each player could be tagged for location, if the rules were to require comparison of, say, foot positions alone. Sensors in ball and boots could leave VAR "human error" behind: no lines to "interpret"; no worry for angles. It works for goal line tech. Should be doable for offsides.
VAR inserts human judgment where none is needed.
