I don't think he'll change much until he sees the game plan he used against melbourne in the fist trial can't/won't work. This has clearly been the plan since the utillity spree started
He'll stick with Hutch and Burton, play Hutch both sides, get him straighter, Burton left and use Salmon for shape out of first receiver. Curran on the bench for impact/starch. Mann for ruck speed/ball playing, insert other as large as are available forwards, Hughes plus someone else
Until they catch and hold the ball for repeated sets to test the theory, he won't change because he doesn't know if it's the wrong plan yet. In any science experience you control as much as you can and vary one thing. We didn't control shit on the weekend and while I hate dissing on the refs, he was awful. So there's no way of knowing which of them is the problem, yet. Except maybe Taffe needs a spell to get his confidence back if Tracey is good to go.
