Nah, the problem is that they aren't suited to anything more than really general comparisons. It is hard to tell whether someone really deserved one or not and they can get inflated by playing in a good team. It is too easy to pick them up for throwing the last pass in a back-line maneuver and a lot get awarded for kicks too, which often muddles them further.
You just need to be able to appreciate their limitations when you are looking at them, particularly using them to form really specific comparisons between players. But they do alright for giving a rough guide.
They are obviously not as good as actually watching the game. However, I don't have the time or the inclination to make a video of Dugan's game to justify my views to a couple of Canberra fanboys.
Please make one of his Origin debut and include every time he chimed in to touch the ball in attacking raids. This will prove your point beyond doubt.
