Hamish Hartlett must stand up, says Power coach Ken Hinkley Power game-breaker Hamish Hartlett has to learn how to deal with tagging, coach Ken Hinkley says. PORT Adelaide coach Ken Hinkley is not cutting his players any slack as they cop the price of a flying 5-0 start to the AFL premiership season. The respect the Power has craved so much this season is now a double-edged sword. Star players are under greater opposition attention. Port's game-plan is under greater tactical analysis. As gamebreaker Hamish Hartlett deals with the obsessive attention of taggers, Hinkley expects his midfielder to find a new strength to his game rather than rely on his team-mates. Hinkley notes Hartlett's team-mates should be giving more, regardless. Tomorrow at Etihad Stadium, Hartlett will still be tagged, despite Carlton not having its best shadower, Andrew Carrazzo. And the Power team in total has to deal of finding a new cog after being found out against Richmond last weekend. To Hinkley, the notion of the Port team lifting to make up whatever is denied by Dennis Armfield sitting on Hartlett is all wrong. "Those individuals themselves have to step up - Hamish has to step up," said Hinkley of Hartlett, who was held to just 10 disposals last weekend. Travis (Boak) has been able to do it quite well. Hamish is getting some experience on what it takes to be an elite player in the midfield. He has to step up himself. You will always be okay if the team together steps up. We can't rely on one player. We're a club that wants to rely on a team performance. You should never be able to predict the players who are going to stand up on the day. If the team plays well, they'll identify themselves because of team effort. Port last night made three changes to the 22 who failed against the Tigers, recalling ruckman Matthew Lobbe, former captain Dom Cassisi and forward Paul Stewart. They replace tall forward Daniel Stewart, defender Campbell Heath and first-gamer Sam Colquhoun. Hinkley maintains breaking the losing cycle at Alberton is more about what the Power players are not doing - rather than what AFL opponents are throwing at Port. "We didn't stay true to ourselves in the way we went about defending - we did not defend as hard as we needed to," said Hinkley. We allowed Richmond clearly too much uncontested ball and they made us pay a price. We know our best method is that when we are defending really hard we give ourselves the best chance to win. We were put under the microscope a bit more - and we did not handle it.
