The Lions Playbook Ep. 5: The Screen Game
Bubble Screen
Up to this point, all the WR Screens create lanes to the inside, the bubble screen works from inside to out as the slot receiver moves away from the quarterback at the snap and the outside receivers will block the corners in front of them to seal the edge.
Bubble screens leave the man covering the target receiver unblock in an attempt to force that player to fight around the other blocks to get to the tackle. This is a variant that Detroit has not run often, but here it is used in a trips set against the Washington Redskins.
