What's the Difference Between a Free Safety and a Strong Safety?

Before we get into defining safeties and their roles, it is important to first understand the following football terms:

The Secondary

football secondary

The free safety and strong safety are both members of the secondary.

The secondary is a group of players in the defensive unit that line up in the defensive backfield or the area behind the line of scrimmage and the defensive line. The safeties serve as the last line of defense between the opposing team's offense and the end zone. Safeties can also be used to blitz or defend the run.

The differences between a strong safety and free safety are based on the following:

Free Safety

Football Free Safety

The free safety positions himself on the weak side of the field.

The strong side is the side of the line that the tight end lines up on. The other side of the field is called the weak side. The free safety is generally smaller than the strong safety and slightly faster. Free safeties also generally are tasked with more pass coverage than strong safeties, since the strong safety has to also focus on the run game. A free safety must be fast, have great tackling skills, and be able to easily read the quarterback.

Strong Safety

The strong safety is a defensive back located on the strong side of the football field. 

The strong safety is generally bigger and stronger than the free safety, and is used more for run defense. They will typically be lined up closer to the line of scrimmage than the free safety, as they are tasked with stopping the run on a running play that breaks through.
