Certain football historians correctly point out that the forward pass is not permitted in rugby football and therefore see the emergence of the forward pass as a critical development in the evolution of association football (and for this reason do not acknowledge the role of the public school games). They forget, however, that passing the ball forward by "kicking" is not only completely legal in Rugby but also is a regular tactic employed in most matches—particularly in open, running play. For this reason the public school games can claim to be origin of the forward-passing game. Passing the ball continues to this day in surviving traditional public school football games. Even in Harrow Football, which is essentially a dribbling game, the ball may be chipped into the hands of a team-mate.
