I agree with you. His defence is bad, but that's not really the issue. The issue is his attacking play - it's not as good as people think.
That's what I was getting at in my post... His relegation to Wenty is not all about his defensive shortcomings I don't think. His critics harp on and on about what a dreadful defender he is, and that's fair enough, but there has to be more to it. To me, it's the pushing of silly passes early in tackle counts, or trying a chip n chase inside your own half (V the Bulldogs), the inability to build pressure and force the opposition in to line drop outs. He's been like that since he came in to first grade. I can only think that the team trains one way during the week and Sandow goes out and plays a different way come game day and BA has had enough and feels he can't get through to him anymore.
Jamie Soward kept his spot in the premiership winning Dragons team despite having a reputation for being just as poor a defender as Sandow, and he had probably less strings to his bow than Sandow does... but he followed a game plan and played to his strengths, ie his kicking game, to help drive his team towards a common goal.
