I was watching NRL on Fox and they were discussing the obstruction rule and linking it to the way we have always understood the old shephard rule. That is, if you run behind one of your own players and the defense is at a disadvantage then it is an obstruction/shephard play. One thing that was discussed and I thought made sense for future rulings and for fans' clear understanding is if the player receives the ball and is on the inside of the player in front running the decoy (which means that they have to run behind him to continue the play) then that is an obstruction. They showed the Inglis try against Manly at the start of the Storm game and Inglis clearly receives the ball on the inside of the decoy runner who obstructs Watmough's view of the pass. I had my doubts about how 'clean' that play was when I first saw it but Inglis had so much room it looked acceptable. For mine looking at it again it should have been No Try as it was a deliberate shephard. Manly have been pinged for obstruction for years and this idea seems to make it it an easy assesment of the legality of a play. Any thoughts on this or better ideas?
