When disc is in the center, Red-5 and -6 sag off to defend the underneath, while Red-4 and -7 sag to defend deep huck. It's important that Red-6 focuses in the interior lane. Red-3 can sag off the handler to help defend an in cut from Blue-7. Do not sag off more than you are able to recover to your assignment.
If disc starts on side, bracket shifts over. Red-6 and -7 play tight on the unders. Blue-4 is horribly positioned to receive anything, so Red-4 shifts over top to help with the deep. Red-5 can also sag off to help with the unders.
