In football, what is a safety?
If you get tackled in your own end zone or lose the ball out the back of the end zone then the other team gets two points and you kick them the ball.
Like your the person who is on the sides and if you get the ball you run it.
When the quarter back or any other player of the offence gets sacked with the ball in the end zone. Then the other (defence) team gets 2pts.
When the ballcarrier is tackled in the end zone, it is called a safety. It gives the team who tackles the player two points.
A ball guard, most needed
