Let's say Dimma has to choose between two players:
Attack: 10
Defence: 1
Defence: 10
Attack: 1
Which one do you choose?
The defensive one, of course. Because the guy with 10 Attack is more capable of lifting his defensive game to a 6 or a 7 than the defensive guy is of raising his attacking game to a 6 or a 7.
Anyone can defend if they put in the effort. So why don't they? They know they'll get a game. What's stopping McDonough, Lloyd, etc from being even harder than Morris? Just their mindset. That's all. It's nothing to do with ability. And the job of a coach is to shape mindsets to create a better culture to win games.
There's at least 10 blokes on our list that are a bit soft and there's absolutely nothing stopping them from lifting their defensive intensity except for their own mindset. As soon as they can match Steve's mindset, they'll get a game. In fact, they'll be guaranteed a game. And we'll be a much better team. That's the way I see it.
