I don't think it would be hard at all. Under Hardwick we have regularly implemented different styles. Think it was last year we played a block of games (and won them) with a massive increase in uncontested marks, a real kick-mark, kick-mark Collingwood Buckley style of play.
At the very least I would have liked to see some movement on what I think is our greatest weakness under Hardwick and the thing that is hurting us the most now, and that is developing an ability to play different modes with the ball.
What I mean by that is under Hardwick you win the ball and you go. The plus one stays deepest and everyone else has licence to kill. Doesn't matter if it was off a quick play or a slow play, if it is first minute of the game or the last 30 seconds of the quarter.
At our best we could get away with it because if we didn't win the ball forward (which was a rare if), we had Rance or Grimes or Vlastuin or Astbury that would provide a mighty defence if it bounced back.
As our ability to win those forward contests has declined, so has our ability to defend behind it just through natural attrition of those stars so we get caught a lot on what they call the turnover turnover. They give it up, we give it back and then they score. The type of goals that come when teams stream forward into a relatively open forward line.
I would have loved McQualter to address that like McRae has at Collingwood. Have modes where you win the ball and go slow, because you aren't set up defensively to charge. Basically it is defending when you have the ball. Or the other one we have never done which has cost us a lot of percentage over the years, take minutes out of the game when you are well up with slow ball use.
Really easy to implement, just a mindset change when you have the ball in your hand.
