AFL Round 21 Tips

Friday 6/08/21

7:50pm Western Bulldogs vs Essendon Bombers @ Marvel Stadium

The Western Bulldogs made short work of the Adelaide Crows last week but it should be much harder this time around against the Bombers.

Essendon were a touch unlucky to lose 109-102 to the Sydney Swans, but it was a tough effort and they should benefit from the outing. However, it all but ended their finals hopes and the Bulldogs could double down.

We think the Bulldogs will be too strong in the second half and pull away for the win.

Betting tip: Western Bulldogs –21.5 @ $1.90Bet @ Sportsbet

Bulldogs by 23

Saturday 7/08/21

7:40pm Adelaide Crows vs Port Adelaide Power @ Adelaide Oval

Port Adelaide continued its domination of the bottom eight teams with a comfortable win over the GWS Giants on Sunday.

Another win looks likely against the Adelaide Crows, who haven’t been able to live up to early-season expectations. They lost by 49 points to the Bulldogs and we could see a similar margin of victory this time around.

Expect bookmakers to have a sizable line for the all-Adelaide clash.

Betting tip: Port Adelaide Power –32.5 @ $1.90Bet @ Sportsbet

Power by 42

7:40pm West Coast Eagles vs Melbourne Demons @ Optus Stadium

We’re not sure what went wrong with the Eagles when losing to Collingwood last week and bouncing back against Melbourne could be tough.

The Demons were explosive when beating Gold Coast Suns by 98 points. We don’t think the margin of victory will be the same on Saturday, but we are expecting the Demons to get the job done.

They have been one of the better AFL sides this season and there is too much turmoil in the Eagles camp to bet on them with confidence.

Betting tip: Melbourne Demons –14.5 @ $1.90Bet @ Sportsbet

Demons by 40

Sunday 8/08/21

2:10pm Hawthorn Hawks vs Collingwood Magpies @ UoTS

Hawthorn was terrific in beating the Brisbane Lions on Sunday afternoon and a repeat could be on the cards against Collingwood.

The Hawks got off to a hot start offensively and defensively. They held the Lions in check for most of the game and it was only a one-sided fourth quarter that made the score line close.

Collingwood scored a 90-45 win over West Coast, so it’s travelling nicely and there is confidence in the Magpies camp.

A close game is expected, but we’re picking Collingwood in a thriller.

Betting tip: Collingwood Magpies @ $2.05Bet @ Sportsbet

3:20pm St Kilda Saints vs Sydney Swans @ Marvel Stadium

St Kilda’s run has come to an end and the 112-81 loss to Carlton wasn’t what this team needed approaching the finals.

Looking to add more pain are the Sydney Swans, who scored another professional and gutsy win against the Essendon Bombers.

Sydney is looking like a premiership contender and they should be able to edge the Saints in what should be an offensive-minded contest.

Betting tip: Sydney Swans –15.5 @ $1.90Bet @ Sportsbet

Swans by 22

5:10pm Fremantle Dockers vs Brisbane Lions @ Optus Stadium

Fremantle showed some fight when beating the Richmond Tigers last week and they’re capable of going back-to-back.

The Dockers had been struggling to show their best form, and although not going well on offense, they showed some good defensive heart.

Brisbane was upset by the Hawthorn Hawks and it wasn’t a good outing. They have been a touch inconsistent of late and it’s not the best form coming into this contest.

Punters get value odds with the Dockers, so we’re happy to take them.

Betting tip: Fremantle Dockers @ $2.63Bet @ Sportsbet

Dates to be Confirmed

Three games have yet to be confirmed by the AFL. Dates and times haven’t been set, but the Blues vs Suns, Cats vs Giants and Tigers vs Kangaroos will play this weekend.

Carlton Blues vs Gold Coast Suns @ Marvel Stadium

Carlton showed their true form when beating St Kilda 112-81 and a repeat effort sees them taking care of the Suns with ease.

Not much has gone the way of the Suns this season and we don’t see that changing over the final few rounds of the regular season.

They were hammered by 98 points against Melbourne last week and that’s not ideal form coming into another tough weekend game.

Betting tip: Carlton Blues –22.5 @ $1.90Bet @ Sportsbet

Blues by 39

Geelong Cats vs GWS Giants @ GMHBA Stadium

It didn’t look overly convincing, but the Geelong Cats got past the North Melbourne Kangaroos by 20 points last week. They would have preferred to win easier, but they got the job done in the end.

GWS were held in check against the Port Adelaide Power, and although it wasn’t a bad effort, they would need to improve to keep the game close against the Cats.

Bookmakers have 31.5 points between them, so they’re expecting the Cats to be much better. We agree, so take Geelong to score a comfortable win and enter the final few weeks with confidence.

Betting tip: Geelong Cats –31.5 @ $1.90Bet @ Sportsbet

Cats by 41

Richmond Tigers vs North Melbourne Kangaroos @ MCG

There is nothing going right for Richmond and that is reflected in betting markets. They are only $1.54 to beat North Melbourne, who are the easy beats of the season.

The Kangaroos have to be respected because of the odds and this Richmond outfit might have put the cue in the rack for 2021.

It could pay to follow betting moves closer to game time, but North Melbourne looks the early play.

Betting tip: North Melbourne Kangaroos @ $2.50Bet @ Sportsbet
