Focus: Allowing a hit to redirect momentum rather than just getting hit out of bounds.
Drill: Groups of 5, four blockers one jammer.
Blockers line up in a flat four wall. Get the jammer to go in with their shoulder across the direction they're going. I.e. going left (inside) around someone right shoulder leads. As they get hit by the blocker (who gives a powerful hit) the jammer uses that momentum to spin* themselves around and go around to opposite side of the wall, or a gap in the wall the blocker who hit hopefully just left behind them (which will be the case if that blocker over committed).
*So if the jammer was hit on their right shoulder their body should turn to their left - this is the 'spin'.
Variation: This can be done in smaller groups one-on-one as well.
