After starting the week at $3.20 with the bookies, the Cats have blown out to $3.30 as the Power, who have been well backed, come into $1.22 from $1.25.

In a quiet week at TAB Sportsbet, the Kangaroos are representing value for money at $2.40 to challenge Adelaide, out to $1.50.

``There has been some real good support for the Roos,'' Sportsbet's Gary Davies said yesterday. ``The Roos show some real value for money.''

One hopeful punter thinks the Roos can bounce back from defeat - plunging $11,000 at odds of $2.55 - earlier this week.

Elsewhere Hawthorn have shortened to $1.14 against Carlton ($4.85), while Richmond ($1.65) are favoured over the West Coast Eagles ($2.10).

Brisbane ($1.25) have been well backed over Collingwood ($3.50).

The high-flying Melbourne is $2.30 against the in-form Dockers ($1.55).

Sydney ($1.60) is tipped to knock over the Bulldogs ($2.20), while Essendon is too short to offer punters any value for money against the hapless Saints.

The Geelong Advertiser's guest punter this week is Geelong West's Joe Collins. Each week Addy Footy and TAB Sportsbet give you a $25 betting voucher for the weekend.

Collins is hoping the Crows can continue their impressive form this season when they take on the Roos at Manuka Oval.

``I like Denis Pagan but I don't think they have what it takes to beat Adelaide,'' Collins said last night.

Each week you can sit in Collins' shoes and have the chance of financial windfall compliments of the Advertiser and TAB Sportsbet.
