This isn't a law change, it is an interpretation. It's not an interpretation - and it doesn't matter who said it was an interpretation. For crying out loud - it will be - hopefully - the implementation of the law as it is written in the book. The divergence from that law by current referees and their fathers, was the abominable interpretation and it is one of the interpretations that have corrupted our game. They allowed generations, in rugby terms, of tacklers, to not release the tackled player as the law said they had to do.
Now some folks are piously stating that they are concerned about the consequences of the law being observed how the law makers intended. This is the world turned upside down.
Please get this point.
To get the players to start obliging to these interpretations during the first few weeks of the Super 14 could very well ensure a penalty fest could be on the cards, with probably a few yellow cards shown to get the message early. Hoo-fucking-ray (more tea Vicar?). Please believe this: it is the only way that the referees will be able to enforce the law as it is written in the book.
Professional players are not always the sharpest tools in the shed but they understand certain things with great clarity. One is that getting yellow cards will make their coaches unhappy and make selectors view them as trouble. This affects their future income and they are crystal clear about what that means. Perhaps yellow cards will make them observe the law as it was intended.
It can be a release for half a second, and a referee might be managing the offside line, and sees the steal, he pings the team to ensure his consistent approach and that player will be forced to lay off the ball from there on, because of the risk of the yellow card. Too bad, too bad. The risk of a yellow card? What a concept. The tacklers have gotten away with the illegality of hanging onto the ball, or the player, or both, for so long some folks are used to it - some actually think it's what the law intended and they make posts to rugby forums to express their concerns that the status quo may be changed. Let's have these players, so used to using illegalities that it is part of the their CVS, get a bit of a culture shock and maybe getting the wrong end of the deal for about 10 years. Then start feeling sorry for them.
This brings me to my second thought, the referees allowing the attacking team more leniency is concerning. The interpretation law on releasing the tackled player will now allow the attacking team to hold on for that extra amount of time. Maybe not - maybe because he doesn't have somebody clinging to him, he can actually present the ball as the law intended he should. An interesting concept - but if he's isolated and doesn't present - ping the bastard as the law says.
But let's see first that he gets an opportunity to get rid of the pill. After that he's on his own.
