I agree wholeheartedly regarding your first two points, but disagree with the notion that contested scrums necessarily contributed to plodding football. Take a look at the 1988 Grand Final and you'll see football at its finest. Fast, tough and a variety of skills on display - not just constant kicking into the in-goal area for another six tackles. Scrums were tense, skilful contests where games could be won or lost. The game has certainly sped up after scrums changed, but at the cost of the game becoming way too predictable. In my view, the contested scrum gave the game greater variety and an "x factor" coaches could not so easily put into their calculations. I've seen so many games lately where teams go fifteen minutes without possession of the ball with a seemingly endless barrage of penalties and constant line drop outs. It looks like a modern version of the old unlimited tackle era.
