Holding the ball decisions range from as soon as you are tackled you are gone, to hold it as long as you like and we'll ball it up. The umpires just wouldnt call a holding the ball decision last night (against both teams) yet last week they were jumping out of their skin to blow the whistle.
Same with the "hands in the back" rule, head high contact (some umpires allow it due to the player ducking his head, some dont), push in the back, marking infringements etc etc. Seems to me there is no set standard anymore of what actually constitutes a "rule infringement", it just depends on the personal opinion of an umpire on any given weekend.
You can have 8 identical tackles from 8 different games this weekend, and there will be 8 different outcomes - if that's possible

No wonder everyone bags the umpires.
