@Isaac, Cairns have been incredibly inconsistent this year, and Adelaide have owned us. I guess the bookies are not convinced that Randle won't be playing much (I'm not, either) and think id he does play, he's likely to tear us apart again.
@Zodiac, I'd be concerned about the same thing. If Cairns win tonight because (or partly because) Adelaide don't field their full strength side, and then somehow pull off an away win on Sunday, the 6ers are in a big hole, mentally, heading into the playoffs. If they do have to face Cairns in the finals, they're also then facing a team that have beaten them twice in the last round.
I think it's crazy to go half-hearted in the final week of regular season.
