Adelaide's hopes of signing Jared Polec rest with Matthew Wright, Bernie Vince and Jarryd Lyon Adelaide's Matthew Wright is considering a move during the trade period. Picture: Luke Hemer Source: The Advertiser CROWS midfielder Matthew Wright holds the key to Adelaide's trade strategy this week that is designed to score Jared Polec from Brisbane and a second-round draft pick from a Melbourne-based rival. Wright, 23, is the potential deal-maker in the slow-moving Polec saga that has - for the first time - Adelaide and Port Adelaide eagerly competing for the same player in a come-home trade. Brisbane steadfastly wants a player - rather than a second-round draft pick - in return for Polec as the Lions deal with the damage of having too many young players seek exits. Port has no player at Alberton prepared to move and will struggle to find a candidate at a rival club. Adelaide, by contrast, has several players prepared to be part of a trade - but to a Victorian-based club and not Brisbane. The list is Shaun McKernan, Ricky Henderson, 2009 club champion Bernie Vince and perhaps Victorian draftee Jarryd Lyons. Wright - who played 17 games this season, the least in his three years at Adelaide - faces a career-defining decision this week when Polec wants to nominate either the Crows or Power as his club of choice. If Wright accepts the chance to sign a long-term deal with the Lions gives him security that is unlikely to unfold at West Lakes, the Polec trade to Adelaide would be virtually secured. The Crows would then focus on finding the second-round draft pick coach Brenton Sanderson has demanded from his recruiting staff all year. Adelaide has no early call in next month's draft - its first pick is currently at No. 42 - as a result of the Kurt Tippett sanctions. Finding that second-round draft pick could come by: VINCE accepting a long-term deal at a Victorian-based club. He is contracted to Adelaide for next season when the 28-year-old midfielder becomes a free agent - and could leave the Crows without compensation. LYONS also is under contract for next season but is being tempted by a long-term deal from Melbourne, where his father Marty played 27 games from 1975-77. The 21-year-old midfielder was a fourth-round draft pick in 2010. HENDERSON is on contract for the next two seasons. And despite keen interest in the Victorian, the Crows are increasingly reluctant to trade the 25-year-old utility. But McKERNAN is drawing little, almost no, interest from Victorian-based clubs. He is destined to have to return to Adelaide where the Crows are willing to persist with the ruckman-forward.
