As Brodders says, fatigue can absolutely be a factor in poor decision-making. And as 123, myself and others observed, players looked tired. Hence they didn't run to receive, or to pressure. And having heavy legs definitely affects your kicking. How was our kicking on the weekend? Was it the worst for the year by a long way? The group having heavy legs is a much more logical explanation than 'they didn't try' or 'they were stupid' or 'we played defenders in the forward line' or 'Dimma's a philanderer' or whatever else people are attributing the performance to.
Or they do extra conditioning work elsewhere than on PRO?
What if we turn things around this week without Lynch and Dusty?
