I agree. These players are offside and must retire. It is that simple. If they do not, then they can be penalized should they interfere with play. The problem is professional players are constantly looking to exploit weaknesses in the LOTG, rather than
respect the
spirit of the players charter. The responsibility is not with the referees, but rather with coaches and players not respecting the obligations they have to observe the LoTG.
[LAWS]Spirit
Rugby owes much of its appeal to the fact that it is played both to the letter and within the spirit of the laws. The responsibility for ensuring that this happens lies not with one individual - it involves coaches, captains, players and referees.[/LAWS]
Application
There is an over-riding obligation on the players to observe the laws and to respect the principles of fair play. The laws must be applied in such a way as to ensure that the game is played according to the principles of play. The match officials can achieve this through fairness, consistency, sensitivity and, when appropriate, management. In return, it is the responsibility of coaches, captains and players to respect the authority of the match officials.
Well I haven’t found highlights of the Bristol game. However he said they did it against Saints. At 4:21 we see an Exeter line-out. Not convinced any offside players contributed to the try scored. The full match is available on the Premiership website, if any one is adept with time stamping an occurrence of this unpenalised offside.
