While Gardiner's understudy Dean Cox rose to prominence, Seaby served as a secondary ruckman into 2005, occasionally being used as a tall forward option with some success.
Gardiner was fined and again suspended indefinitely after a drunken car crash just days later, leaving Seaby to ruck without a specialised backup for a handful of weeks in which he performed admirably.
He played many games in the WAFL in 2008 because of Dean Cox's stellar form (despite a broken foot) and Quinten Lynch's ability to pinch-hit in the ruck whilst contributing more around the ground.
In the same deal, the Brisbane Lions got Buchanan and Brent Staker and lost Bradd Dalziell to the Eagles along with pick number 28 to the Swans.
[1] Seaby suffered an ankle injury in the opening minute of the Swans' 20-point win over the Brisbane Lions and subsequently missed the remainder of the season.
