From a match this week. From the kick off - 3 breakdown offences (2 offside at the breakdown ruck and one tackler not rolling away).
Three inside 6 minutes. Is this the point to issue a team warning and next one in the bin or one further offence?
Taffy, as others have stated no hard and fast rule on when to escalate, you dont give enough detail in your initial posting as too was there a clear and obvious material effect of the 2 offsides at the breakdown, did the attackers go that way, area of the park etc. The tackler not rolling away I can live with if he has sufficiently slowed down the ball to the attacking team.
You must think to yourself are these blokes clever enough to know what they are doing or are they just dumb and unsure, are you being preventative enough, its a 2 way game, if your not helping and assisting them and then just straight up PK them then you may need to look at your preventative to assist you and get the players more onside to what your trying to achieve.
