I can't see complacency creeping in this season. All off-season in the Advertiser we've had stories about the likes of Prismall, Gamble, Davenport and those on the fringe of the club saying that "this is the year we make it big in the seniors." We have such an even list that there's competition for just about every position in the senior side (I think Mooney is the only player with no real replacement). We saw last season that players would slip into the side and would just do their role. I expect the same to continue this year.
As for game plan, I can't see it changing much either. I remember reading once that Thompson said he's formulated four different game plans according to conditions and our opponent. Whether it's true or not is another thing, but to have four different game plans would surely keep opposition coaches guessing. I actually think that later in the season our free-flowing, straight down the guts approach, wasn't as effective at Skilled as it was at the G as Skilled is narrower, and I remember Port sort of set up a midfield zone which was hard for us to counter when they beat us there in Round 21.
I agree with Ash though. If all other 15 clubs incorporate our game plan this season, then it's going to be one exciting season. Bring it on!
