As the trade period draws to a close, Swans senior coach Paul Roos has reflected on a "very, very successful week", with the Club acquiring four new players.

Roos had indicated prior to trade week that the Club intended to bolster their ruck and midfield stocks during the exchange period. The need for ruckmen became increasingly urgent following the sudden departure of star ruckman Darren Jolly to Collingwood.

“Going into trade week, the priorities for us were the ruckmen,” Roos said.

“Obviously we wanted to get a back-up for Darren, and then when Darren decided to leave we needed to get two ruckmen, so we’ve come out of it with Mark Seaby and Shane Mumford.”

Seaby, a premiership ruckman who lined up against the Swans in the 2005 West Coast Eagles side, has played 102 games and is expected to shine in Sydney after being overshadowed by at the Eagles by Dean Cox.

Mumford, who is expected to take on a back-up ruck role, has become the first rookie in history to be traded during the exchange period, following a change in rules this year. He was identified as a genuine talent while playing country football in Bunyip, and played 18 games for the Cats this season.

The Swans exacted a trade with Hawthorn, acquiring Ben McGlynn and Josh Kennedy, whose grandfather John senior was the Hawks' first premiership coach, while his father, John junior, played in four Hawthorn premierships in the 1980s.

The Swans have also retained two first round draft picks in selections six and 14, plus selections 38, 54 and 55.

“We’ve had a very successful trade week, and we’ve also got another first round pick going into the last uncompromised draft, so full credit to all of the football department on a fantastic week,” Roos said.

“We’d also just like to acknowledge Amon Buchanan, Barry Hall and Darren Jolly, who’ve all made superb contributions to the Club over the years, and who will be fondly remembered by everyone here at the Swans.”
