The issue for Digby is that he was not that long ago regarded by some as one of the best wingers in the world. With that accolade comes analysis of your strengths and weaknesses, attacking patterns and defensive techniques etc. In other words, they work you out and shut you down. If you don't evolve, then your form suffers.
He does better with more space and less organised defence (as he should) al la S15 but even his S15 season was a bit quiet. Some of that could be put down to the loss of Quade too. If we can get Quade, Sanchez and Digby to string some games together for the Reds next year it will hopefully reignite him a bit!
