The Adelaide Crows say they understand club champion Bernie Vince's decision to join AFL rivals Melbourne on the security of a long-term contract.
The Crows on Friday traded Vince to the Demons for pick No.23 at next month's national draft.
The 28-year-old midfielder's contract with Adelaide expired at the end of next year.
But the Crows were not yet willing to offer their 2009 club champion a contract extension, and Vince instead secured a three-year deal with Melbourne.
"We didn't want to lose him but I understand his decision to seek some long-term security," Crows coach Brenton Sanderson said in a statement.
Melbourne gave up pick 23, their compensation draft selection received for the move of free agent Colin Sylvia to Fremantle.
Despite the loss of Sylvia, Melbourne's midfield is now signficantly stronger with the arrival of Vince from Adelaide, Viv Michie from Fremantle and Dom Tyson from the GWS Giants.
Adelaide's disappointment at losing Vince was tempered by the looming arrival of ex-Geelong premiership player James Podsiadly.
The 32-year-old, who was delisted by Geelong at season's end, has agreed to a two-year contract with the Crows.
"From a physical and mental point of view, I'm in great shape and very motivated to continue my improvement in the AFL," Podsiadly said in a statement on Friday.
Podsiadly was lured to the Crows by Sanderson, who was a mentor to the 83-gamer when an assistant coach at Geelong, a stint which ended in 2012 when he won Adelaide's top job.
Adelaide's list manager David Noble was thrilled to secure Podsiadly.
"James has plenty of good footy left in him," Noble said in a statement.
"He's an experienced, premiership player from a highly successful football environment."
Geelong premiership castaways Paul Chapman and James Podsiadly were thrown AFL lifelines as decorated Nick Dal Santo quit St Kilda on the busiest day yet of the trade period.
Chapman joined Essendon and Podsiadly agreed to move to the Adelaide Crows, both on two-year deals.
The pair, both aged 32, were delisted by Geelong at season's end, their moves coming as the AFL's trade period clicked into high gear on Friday after idling for week.
Dal Santo left the Saints for North Melbourne, ruckman Shane Mumford's move from Sydney to Greater Western Sydney was ratified, Melbourne gave the Giants a coveted draft pick in return for precocious talent Dom Tyson and Adelaide traded Bernie Vince to the Demons.
Melbourne traded their prized second pick at November's national draft to GWS in return for Tyson, a highly rated 20-year-old midfielder originally selected at No.3 in the 2011 draft.
The Demons also traded their draft picks 20 and 72 in return for Dyson and the Giants' picks nine and 53.
"We have been able to bring in a class midfielder in Tyson, and improve our second draft selection," Melbourne's football manager Josh Mahoney said in a statement.
Adelaide sent their 2009 club champion Vince to the Demons for draft pick 23, while ex-Geelong stalwart Chapman signed a two-year contract to re-unite with his former coach Mark Thompson at Essendon in a free agency deal.
And his former teammate Podsiadly will also re-unite with a former assistant coach, agreeing to a two-year contract with the Brenton Sanderson-coached Crows.
Chapman and Podsiadly will extend their careers until they're 34, with Podsiadly adamant he had plenty of top-level footy remaining.
"From a physical and mental point of view, I'm in great shape and very motivated," he said in a statement.
The Giants on Friday also received ex-Swan ruckman Mumford for pick 35, while St Kilda's Dal Santo ended months of speculation about his future by joining the Kangaroos as a restricted free agent.
The 29-year-old signed a three-year deal with North, with St Kilda expecting a second-round draft pick for the three-time All Australian.
"We are thrilled to have finally landed him," North's general manager of list and player personnel Cameron Joyce said.
The AFL also released compensation draft picks for free agents, with Collingwood getting selection 11 for Dale Thomas, who transferred to Carlton.
Hawthorn received pick 19 for losing megastar Lance Franklin to Sydney while Melbourne were handed pick 23 for Fremantle-bound Colin Sylvia. The Demons immediately gave up that selection for Adelaide's Vince.
The Saints were given pick 25 for Dal Santo while Carlton received nothing, deemed to have broken even with the arrival of Thomas and the loss of Eddie Betts to the Crows.
