I'd go along with that Parky. It's almost like he's trying TOO hard to come up with something special for each game that will counter the opposition. I think he realises that he's basically on trial and he has to prove his worth as a tactician and has, as you mention, micro-managed things so much that the focus has shifted to coping with the opposition rather than attacking them.
I just hope he realises that in trying to be too cute, he's actually hindering his chances of winning the game each week.
