Sometimes you want the players to concentrate on playing the ball rather than just takling 'pot-shots' from distance. This is the time to use line football. With line football, you play a normal game (or, of course, a game modified in any ways similar to those discussed in other 'conditioned games'. The only modification is that the team scores by stopping the ball on the goal line by putting a foot on it. There are no goals to target .... the whole goal line, from corner to corner, is the goal.
We use this regularly as a follow-on from the Keep Ball drill.
