Yeah, like I said to CQDog - some of his defensive efforts were embarrassing this year.
As far as the regression goes, I believe some of it is explained by him trying to tighten his game eg. We saw less of his torpedo bombs and more weighted kicks. He obviously didn't forget how to do them, so why? Most likely he's using a more controlled kick in an effort to land the ball closer to the try line. I think if you view this year through that lense, it explains a bit - giving early ball to Kikau to try getting him involved.
All that said, he definitely needs to show improvement in areas he can control.
