Matto, I think you raise some valid issues, and some invalid ones. In the spirit of free debate, I will have a crack at the ones I think you got wrong.
3. Scarfman: "...watch the AB's returning, Owen Franks, Kevin Mealamu just hitting a ruck from the Springbok side..." (WRONG: No ruck was formed = general play - no offside.)
But they are in front of the ball. As Thomond points out, you still can be offside in general play if you are ahead of the ball carrier. This is the main problem with a few of your points- the tackle is not a lawless zone where people can do whatever they want, there still are rules regarding offside, staying on feet etc.
4. Scarfman: "...Jerome Kaino taking the ball up, and again you'll see Owen Franks was ... 3 or 4 metres offside..." (WRONG: Tackle, not a ruck - and No. 3 Franks was pulled by the arm by no. 2 Smit.)
Again, he is in front of the ball in general play and thus offside. It comes back to Law 11: “In general play a player is offside if the player is in front of a team-mate who is carrying the ball, or in front of a team-mate who last played the ball.” Franks is offside and shouldn’t be touching anyone.
6. Scarfman: "...Conrad Smith runs around and tackles Kirshner...about to enter the ruck, and tackles Morne Steyn..." (WRONG: Kirshner, Smith, & Ranger arrived at the tackle simultaneosly and caused the ruck (no offside). Morne Steyn engaged Smith from behind and pulled him back.)
Two points here. Firstly Smith comes in from the side. Secondly he clears Kirchner 2-3 metres past the ruck, to the point where I would consider it obstruction. He effectively took him out of the next phase of play.
9. Scarfman: "...2nd one is a bit worse... Franks it is again just lying all over the SBok side of the ruck..." (WRONG: Franks is clearly 1-2 metres away from the ruckon the ground in contact with no-one at all.)
But they do impede the Springboks access to the ruck. Again a subtle tactic. They can’t get up any speed to hit the ruck, because they have to hurdle Franks and Woodcock to get there. And as they are in front of the ball, they are offside and are very slow to roll away.
10. Scarfman: "...McCaw comes in from the side and falls down in front of the ball..." (WRONG: No.7, McCaw is the first AB to the tackle - not ruck)
Law 15.6d “At a tackle or near to a tackle, other players who play the ball must do so from behind the ball and from directly behind the tackled player or the tackler closest to those players’ goal line.”
McCaw comes in from the side. Penalty.
11. Scarfman: "...here's one where they dive over the ball, won't let the Bok player release..." (WRONG; Those players "diving over the ball" were tacklers, and Franks's tackle was "slipped" and had no effect on the ruck from the ground, clear.)
Doesn’t matter who they are, they are still off their feet at the ruck. Mils is the main culprit here, at least Franks tries to roll away. He has a HUGE effect on the ruck at the ground, as the Springboks can’t drive through their side of the ruck because Mils is lying there like a piece of lumber.
14. Scarfman: "...Russouw breaks a tackle, Boks get close so McCaw does that (Rolland says, 'not going through the gate'." (WRONG: McCaw in fact, was the tackler and releases then gets to his feet & contests the ball legally - textbook.)
McCaw is not the tackler. Law 15 states “Opposition players who hold the ball carrier and bring that player to ground, and who also go to ground, are known as tacklers”. McCaw did not go to ground, he keeps his feet the whole time. Penalty.
16. Scarfman: "...McCaw dived over the ball, penalty..." (WRONG: McCaw did, in fact, dive over the ball but it was loose after SBok No.7 was tackled with no other Bok over the ball - no ruck.)
There are still players over the ball when Richie goes off his feet. He knocks one of them over actually. As there was still contact over the ball, it is still a ruck. Penalty.
Hope this wasn’t too long, but my basic point is the tackle is not a lawless zone where you can’t be offside. I hope I made some sense in my making of this point.
