I know every bodies just going to say that I'm just a one eyed Raiders fan, but Rickys' not wrong on this one, It's been a tactic that has been consistently used against our team since the Sharks first did it in the semi last year.
You can't see it unless you're at the game because most of the time they don't show the defensive line on TV, but teams will stand 8 meters or so back (more often then not even the players right in front of the ref) and go before the ball is played (normally as our player is placing the ball on the ground, not when it's touched his foot, but sometimes it's even worse) then on top of that they'll add the wrestle to slow the play the ball down (admittedly every team has to deal with the wrestle).
They rely completely on the ref not calling them offside, or calling them offside so rarely that the penalties that they incur are worth it the reward of being able to completely stunt the speed and effectiveness of our attack.
Now don't get me wrong I'm sure other teams are facing similar tactics being used against them (the Warriors seem like a team that this tactic would work really well against), but as I said before with this tactic it's not as obvious because can't really see it in action unless you're at the game because 90% of the time you can't see if the opposition is back on side or if they're going early when watching on TV.
The problem isn't really that teams are using this tactic (or others like it), if you can get away with it why wouldn't you, the problem is with these ideas of the referee controlling the 'flow of the game' and 'interpretations of the rules' that have taken root in the reffing ranks in recent times.
If refs stopped worrying about the flow of the game and just worried about reffing the game this tactic and most of the other rule bending (or outright outlaw) tactics would die out in under month because the penalty would out weigh the reward and coaches would start coaching the players not to bend the rules and guess what, the game would flow just fine.
