Great posts Teach, I would add that at times in OZ there is an aversion to scrummimg , especially at lower levels of club rugby, I think this eventually causes problems all the way as not the same pressure put on forwrds to hold their spot with good tighties coming through lower grades to pressure them. Case in point for me is the number of times I have seen in first and second f
grade in Brisbane, as soon as some teams have been getting dominated in scrums, they simply pull the old prop injured no front rowers trick and end up with uncontested scrums, it unfortunately easy way out of problem. I recall a game in first grade last year where team did it against our team, when I (who is known to get agitated with things like this) pointed out to their coach after game I thought it was outside spirit of game, he laughed and said don't show your hand so early in game. I am surprised over the last few years how many teams in lower grades(including colts) simply start games with uncontested scrums.
I also agree with your comments re body positions, when I coached both here and in NZ the very first thing I always insisted on was body position, both in scrums and second phase, I stated in another thread I believed the Wallabies allowed Irish to get under them in rucks, and I always put a most forw3ards in front row on a a scrum machine to try and get body positions in all phases, as I think it important for front row to always bend from hips, and think the same helps in rucking etc.
