The strong safety tends to play closer to the line than the free safety does, and assists in stopping the run. He may also cover a player, such as a running back or fullback or H-back, who comes out of the backfield to receive a pass. A strong safety's duties are a hybrid of those belonging to a linebacker in a 46 or 3-4 defense and those of the other defensive backs, in that he both covers the pass and stops the run.
