Create one large pack -- usually I simply put everyone from the session into one pack, but I'd say max 15 per pack if you happen to get big sessions.

Coach nominates a jammer and an offense - they drop to the back of the pack.  The aim is for them to get through to the front together - ideally with the O creating gaps and the jammer following closely.

The pack is actively blocking as individuals -- it gets pretty messy if you let them start to wall up (but feel free to play around with it) .

If the jammer gets out without the O, they’ve lost.  The objective is to follow the O through the pack.

This drills leads into SCurve offense, sticking with your O, O-J comms.

Offense and jammer work their way together through the pack.
