Physical contact from behind or unsuspecting an opposing player is dangerous and might lead to severe injuries. When players see the contact coming, they have the time to prepare and brace. This lacrosse serves to protect every ball carrier while in the vulnerable position, compromised. As the committed penalty has a physical nature, the penalties can be considered situationally dependent and subjective. But, if an offensive player intentionally turns his back to make contact with a defending player, the opponent-defender will not be called for a push-from-behind rule violation.
