IT was more of the same from Port Adelaide last weekend against Fremantle - competitive for the most part, but simply not good enough to get the job done.

North Melbourne also lost, to the Western Bulldogs, a game they would have expected to win. They'll expect to win against the Power, too, but not if Primus' men find the form that saw them beat St Kilda in round one.

THE FOUR POINTS
PORT ADELAIDE
1.Jay Schulz should return to Port Adelaide's forward line this weekend, which would be a huge boost given they kicked their lowest score of the season last weekend. Schulz is deadly accurate in front of goal and his general competitiveness is also something the Power desperately need. He offers the side a genuine target when attacking and, with the possible return of Chad Wingard, Port's forward line could appear more structured and capable on Saturday.

2. Lapses cost the Power dearly against Fremantle. A goalless second term and a four-goals-to-one final quarter meant they didn't stand a chance. While they were again within reach at three quarter-time, Port must simply play more consistent football if they are to get the win the players say will spark their revival in 2012.

3. Port's movement out of defence was hard to watch at times against Fremantle. Not only did they appear incredibly slow, they looked a side that lacked any confidence to hit targets. It's easier said than done, but the Power need to move the ball quickly, play on and take risks when mounting an attack … the question is whether their players are capable of doing so.

4. Port Adelaide's skills against Richmond were deplorable, but it was an awful day and so they were forgiven. But against Fremantle the weather was perfect and they still struggled to hit targets consistently. They recorded 10 more clangers than Fremantle, with turnovers still costing the side at vital points in the game.

NORTH MELBOURNE
1. North Melbourne's loss to the Western Bulldogs was its most disappointing of the season. The Kangaroos entered last Sunday's game as strong favourites but were jumped by the Bulldogs and although they lost by only 18 points they never looked like winning. North should again start favourites this Saturday against Port, which has not won since its round one victory over St Kilda. It's a game North must win to keep its finals hopes alive.

2. Coach Brad Scott will put a strong emphasis on contested work at training this week after the Bulldogs dominated the Kangaroos at stoppages and in the air. The Bulldogs won the contested possession count by a whopping 54 last Sunday and Scott was adamant after the match that was not how North played football. You can expect the Roos to lift their intensity around the ball against Port, while they might also recall inside ball-winners such as Levi Greenwood and Cruize Garlett.

3. With Hamish McIntosh likely to miss with a knee injury, will North bring in tall utility Cameron Pedersen to support Todd Goldstein in the ruck or will Drew Petrie resume the support role he played so effectively last year in McIntosh's injury-enforced absence? Taking the latter option might also be a way of getting Petrie into the play more often after his slow start to 2012 on the forward line.

4. North has an outstanding record against Port, having won 19 of their 26 games since the Power entered the competition in 1997. The Kangaroos won their first nine matches, finally dropping a game in round eight of 2003. North's recent record against the Power has been almost as good, having won five of their last six clashes. Even at AAMI Stadium, North has beaten Port six out of 11 times, including three of their last four encounters.
