It's more likely the extra fatigue those up the field are placed under when the balls coming in are hardly ever marked and the resulting spilled ball just shoots straight back out, almost a no crumbing forward line not helping here as well AF. We are also devoid of quality crumbing smalls who can pounce and snap!
In addition we are so inaccurate (in general) that there is little time to recover, kicking so many behinds with the opp immediately playing on from the square much of the time. No time to recover, set up and defend effectively.
Also it doesn't help when for example, an experienced player like ANB, takes a mark close to goal then fails to use up the shot clock and take a set shot at the goals. Instead playing on almost immediately to kick around the corner and missing. With the resulting kick in coming almost immediately back at our press / defenders and mids. It's mind numbing non awareness like this that causes extra fatigue and impairs our defender's ability to set up effective defensive structures and maintain the pressure for repeat entries and additional scoreboard pressure. The opp often scoring immediately on the sling shot as a result and making our previous efforts null and void.
This is as much of a list issue as it is a coaching/training issue. So may players just "doing" without assessing or seemingly little if any any awareness of playing the percentages and eaking out every little advantage for the benefit of the team.
Huge pre-season fixes on the track and trade table required if we are to improve enough to make finals next year.
