Arcoss is defined as which action?

• A. A defensive zone formation
• B. A sideline call
• C. The act of marking the opponent across before a pull
• D. The method of a high release throw

Answer: (C)

Arcoss is about the defender positioning themselves to mark across the thrower before the pull. The defender steps in front and to the other side of the thrower, shaping the throwing lanes right from the start and making the thrower choose a target under pressure and at a less favorable angle. This pre-pull marking helps disrupt the thrower’s rhythm and can limit the release options available immediately after the pull. It’s not about a defensive zone setup, a sideline call, or a throwing technique—those describe other aspects of the game, whereas arcoss specifically refers to this cross-body marking action before the pull.
