Yep fair point Braveheart regarding scrum dominance and Reds lack of wins, that has been largely due to backs not executing after a good forward platform, in my opinion. I think you need to chase the scrum penalty each time though when you've got a dominant scrum. Obviously the hope being the opposition end up with a yellow card.
I remember a few games last year where I thought the Reds were very hard done by and drew repeated scrum infringements and not drawing some cheese from the ref.
It depends where it is on the field I think. It's not often that you get penalty advantage and still have a good platform to work from. Your number 8 is very unlikely to be able to pick it up from the back so that option is gone allowing defenders to reposition.
Maybe the backline would be converting more opportunities if the emphasis was on giving them good attacking ball when inside the opposition 22?
I guess my overall take is that it's probably worth reviewing the emphasis on the scrum because it hasn't provided them nearly the advantage in games that many people would think it should. The Reds look much better this season because their forward are getting on top more often in general play. The last few years of the Waratahs beating the Reds has generally involved the Reds smashing the Tahs at scrum time but being outmuscled in general play.
