Quote: snowie "well the rules above come from the rfl and is clearly within whats in red, are you looking at Crowther being off side at the charge down or mason who was at the side of the play the ball?'"
You are mixing up 2 different rules. The bit you quoted is written for say, being in front of the kicker.
If you carry on down the page that you linked to you will find this section:
“Out of Play” as opposed to “off side” 3. Players who are out of play at a play-the-ball (Section 11), a scrum (Section 12), a kick off or drop-out (Section 8 ) a penalty kick (Section 13) or a free kick (Section 13) are not put “on side” in the manner described in para 3 above. (Seeappropriate Sections).
It's kind of ironic that you have told him to read the rest of rules whilst he's at it but didn't bother doing that yourself.
It wasn't a try, but it didn't matter in the end so I can't get too upset about it. We got lucky with the red card so it's swings and roundabouts.
