where do you punt from after a safety
Safety (gridiron football score) After a safety is scored, the ball is put into play by a free kick. The team that was scored upon must kick the ball from their own 20-yard line and can punt, drop kick, or place kick the ball. In professional play, a kicking tee cannot be used – however, a tee can be used in high school or college football. Once the ball has been kicked, it can be caught and advanced by any member of the receiving team, and it can be recovered by the kicking team if the ball travels at least 10 yards and bounces at least once or a player of the receiving team touches the ball.[8][9]
Back-pass rule Goalkeepers are normally allowed to handle the ball within their own penalty area, and once they have control of the ball in their hands opposition players may not challenge them for it. However the back-pass rule prohibits goalkeepers from handling the ball after it has been deliberately kicked to them by a team-mate, or after receiving it directly from a throw-in taken by a team-mate.[1] Back-passes with parts of the body other than the foot, such as headers, are not prohibited. Despite the popular name "back-pass rule", there is no requirement in the laws that the kick or throw-in must be backwards; handling by the goalkeeper is forbidden regardless of the direction the ball travels.
