After a safety, the ball is spotted on the 15-yard line for the free kick. These are the major differences between the two games. It is still important to note that the basics of the game are still to block and tackle. Fundamentals still have to be taught just as in 11-Man football. Just as in 11-Man football, each team must develop it's own style of play.
Some teams run the ball effectively, while others rely on the passing game.
The point is, just as in 11-Man football, each team must decide what it must do to win. Differences DO exist between the two games. Players must still block, run and tackle. That is what the game is all about. Still one ball, two end zones and two teams that must control the ball to win.
