At the time I pass the ball to my teammate (you) There has to be someone from the other team BETWEEN you and the goalkeeperIn other words, when the ball leaves your teammates foot, the CLOSEST person to the goalkeeper (north/south wise) should be his own teammateThis is based on where you are ONLY ONLY ONLY when the ball leaves my footShould you be closer to the goalkeeper than the defender/his own teammate when the ball leaves my foot, you are offsidesIt is difficult to explain in any language despite of mother tongue! Think almost opposite of American football. If a WR gets behind a safety BEFORE the QB throws the ball, that's perfectly fine. In soccer, that would be offsides. Now think back to the Denver game, I think Joe Flacco threw the ball before Torrey was open on Champ Bailey and that would be the perfect pass in soccer. All about timing and speed
