Actually, why haven't we focused on set plays.
The biggest sadness in bringing Sheens back, None of his crazy set plays.
I actually see it differently.
Defense is how strong the team is. It only takes one or two weak links and teams know where to target and score.
Attack, you need co-ordination between a few players and skills in the scorer and play maker. Yes when the whole team can threaten it is better, but you don't need every player involved in the attack.
You need every player involved in the defence. One or two weak links, and you will get 4 against.
