What it means for Port Adelaide: The Power can build on their sensational win against reigning premiers West Coast in Perth on Good Friday. With a 4-2 start, the Power would be set up nicely for the season.

What it means for North Melbourne: The Kangaroos will be desperate to get off the bottom of the ladder. It's been a shocking start to the season, hitting a new low with last weekend's 58-point loss to Essendon.

How Port Adelaide wins: The Power's gameplan is built around frenetic ball movement, taking the game on and playing high-risk, high-reward football. It doesn't come off all the time, but when it does, it's hard to stop.

How North Melbourne wins: It's all about contested ball for the Kangaroos. Their midfielders have to establish themselves on the inside and give their outside runners like Polec and Aaron Hall a chance to hit up their forwards on the lead.

The stat: The Power have won their past four games against the Kangaroos by an average margin of 34 points. North Melbourne's last win over Port Adelaide was in round three, 2014.

The match-up: Tom Jonas v Ben Brown

Jonas did an outstanding job on Brown in the corresponding fixture last year. Brown kicked four goals, but two of those came when the sting was out of the game. Brown is the eighth-ranked key forward in the Official AFL Player Ratings, and 98th overall, up against Jonas, who is the 14th-ranked small/medium defender, and 133th overall.

It’s a big week for: Jared Polec

The Kangaroos wingman faced the Power in the JLT Community Series, but there will still be plenty of feeling in his first home and away game against his former club. Polec,  who joined the Kangaroos on a lucrative five-year deal, has been one of their shining lights in a tough start to the season.

Big call: Robbie Gray kicks five goals and has 20 disposals in a best-on-ground performance.

Prediction: Port Adelaide by 32 points
