Well, I've had a look and I guess I can't add to much to the discussion above. In particular, I agree with NTA:
What I noticed about the Heineken final - and maybe it was just the two teams involved - but there was bugger all in the way of decent scrummaging, and bugger all in the way of a ruck contest, compared to S14 generally. Its hard to make a comparison based on the few games of NH rugby I've seen this year, but with penalties at ruck time there's just to attacking the ball.
At ruck time, the defending team looked too scared to counter-ruck, especially in the red zone.
In the scrums, it looked to me that both packs stopped scrummaging whenever a scrum started to pear-shaped. Fewer collapsed scrums that way, which was a weclome change.
Cheika's handiwork was all over Leinster. Backing up, and looking around for back-up, and
expecting it to be there.
The biggest differences I noticed were the cliches, and I can't argue wioth them. NH teams weren't looking to score tries, they were looking for field position and 3 points. Not once did the HEC boys look to run from their own 22 or counter attack with the expectation of 5 points. The SH boys looked fitter, faster, even stronger, and they executed everything with more speed and accuracy.
No difference in mauling, and not much difference in the kicking game. I was suprised by the number of mid-field bombs in the HEC game.
Not too many tap'n'goes in the HEC. I guess it is only this that makes S14 look messy, because I would back the Bulls in the set peice against Leinster.
Oh - last thing - there was a noticeable difference in tackling. S14 teams were tackling in such a way as to get caught between the ball and the opposition halfback. HEC refs wouldn't let them do this as much, I believe.
