Aku has been a target since the year he was dropped from the NSW team in 2012. The writing was on the wall early in that series and possibly before. We can argue about when his formed has dipped or seemingly returned but the facts are he has not addressed or been able to improve the areas of his game that needed attention. Teams have targetted him successfully for years now. Yes he is a confidence player who lacks confidence when defending, placed under the high ball or scooping the ball up off the ground and with his general with ball security when returning out of his own end.
At his absolute consistent best with minimal mistakes you have him every day of the week.
Either way, staying or leaving, I hope he plays well. However, if the rumours are true, you can't blame the new coach for planning ahead and making some tough decisions considering Aku is collecting just under 10% of the cap.
