Coaching is a team effort with, as has been previously stated, a lot done during the week with contingency planning also included.
That said 3 points I think the coaching panel are doing a great job with
1/ Defensive structure - We are not being sucked down the ground too far therefore allowing plenty of options if the ball either comes out of our forward line or if we need to reset on the way in. Time and time again on the weekend as the Hawks looked to release all they saw was a tiger wall (often 2 layers) or if during a forward move the kick in opportunity was thwarted we had the release option backwards to reload.
2/ Forward rotation - The rest forward of Lids, Cotch and Dusty is working really well. All are really good marks for their size, creative and quick which has added a new dimension to the forward line.
3/ Team running allowing for lateral ball movement - the movement from back to forward has been materially aided by hard, team running. We move the ball generally with pace and precision because there is invariably a team mate available to either run forward or if required move laterally either via run or kick across ground to open up. Whilst our disposal has improved, I think this is at least in part due to the options we create for ourselves therefore meaning less kicks are under the highest pressure levels.
Edit
2 more things worth noting
a/ We concentrated on not allowing opposition run on's. I think I noticed after each Hawthorn goal Kingy would start the next centre bounce defensive side of the square. I assumed this was to provide support in the case of a follow up centre square break. This might have been the difference against collingwood had we employed it earlier in the season?
and
b/ The willingness to hunt the contested ball, particularly in packs. Morris has been the most obvious here but if feels like a team trait. One that has seen us turn around contested ball stats.
