Port Adelaide legend John Cahill gives his seal of approval for black-and-white heritage tribute Port Adelaide great John Cahill announcing his retirement from coaching back in 1995. Picture: Ray Titus. PORT Adelaide legend John Cahill has backed the Power's decision to wear the traditional black-and-white jumper in its farewell from AAMI Stadium in August. And the man who guided the Magpies to 10 of their 13 SANFL premierships at the West Lakes arena says the new-look Power is again upholding all of the Port Adelaide traditions built in the "prison bar" guernsey. "I can see the old-style of Port Adelaide coming back," said Cahill yesterday as the Power launched the jumper at AAMI Stadium. And I don't see any reason why they won't keep winning. They're confident and the way they are playing there is no limit to where they could go. They can achieve anything if they want. Port will wear the black-and-white strip for the third time in an AFL premiership match when it hosts Carlton in the last AFL home-and-away game at AAMI Stadium in late August. The club's special run of 1600 replicas jumpers - that will sell for $260 to members - was keenly taken up by Power fans yesterday. Victorian-draftee Robbie Gray yesterday embraced honouring the black-and-white jumper in the farewell to AAMI Stadium. "As soon as you walk into the club you appreciate the importance of its history," Gray said. In round 23, we play on AAMI Stadium for the last time remembering how proud the club is to have won 13 premierships on the ground. It is a great opportunity for the boys today to recognise how those flags set up the club for the AFL, and we're looking forward to honouring those achievements.
