*Handler defender sets a straight up mark on the disc, and the two off handler defenders sag into throwing lanes. *Secondary is comprised of a deep deep and three mids. The three mids are playing person d on offensive players as they come into their zone, and passing them off as they leave. *Priority for the three mids is sitting under the cutters and taking away the primary threats. *As the disc swings to a sideline, the handler defender sets a straight up mark forcing back to the middle of the field. The middle handler sags into the throwing lane and the far side handler can look to pinch in (more if it's windy). *If the disc breaks through the secondary, the 3 handler defenders must catch up and contain while the secondary should drop and stop the next immediate threat.
