Defence will be less of an issue(but still a problem) if our attack was more direct and efficient, being able to dominate some field position and induce fatigue into the opposition so that it is an arm wrestle beyond 6.25mins.
When the attack is clunky and old school predictable the heads drop off and the enthusiasm to put in defensively is reduced(especially with young players), you don't feel the effort in defence will be rewarded at the end so the 1% effort plays start to drop off and it becomes a chain reaction.
One out passing from Croker to a short lead runner is boring as f99K, DCE and Foran work well with passing variety that is either short with speed and running momentum or a distant crisp flat wide lateral pass to mix things up---going through the short pass off the ruck and second man play to the half is cumbersome and doesn't get you to the edges quick enough.
When Croker passed a flat face ball out front in the second half Manly almost created an overlap---we need to gain confidence off the ability to score points more easily and the defence will want to show up after that.
The very early exchanges the Roosters were looking up before receiving the ball with some good first contact defence, we just need to give the team more reason to sustain it because at the moment the mind is weak as sh(t and the dropping of heads way too easily for a first grade squad.
The beauty of Ballin was that he allowed Foran and DCE space from the ruck due to his crisp long service and Manly could play laterally very efficiently and catch teams out, making yardage on the edges---we really miss this but need to evolve beyond this limitation also.
