The Kangaroos are in free fall. They have lost six of their past seven games and, while they are still two wins clear inside the top eight, a defeat against Collingwood at the Dome on Friday night would have the Arden Street army very nervous. The Roos lost to Port by 28 points in round 17 despite having more scoring shots. They booted 10.17 against the Power - and we don't think they will be that inaccurate again. Our money is on a Kangaroos/Kangaroos half-time/full-time double, which is paying about $2 with most bookies, and Collingwood's Adam Treloar to get at least 35 touches ($2.80 with Sportsbet). He had 36 against the Crows last week.
