Jack won a tight vote count on Friday night, collecting 553 votes ahead of former Geelong ruckman Shane Mumford (545), and former Hawthorn midfielder Josh Kennedy (542).
The result was no surprise to fans of the tough midfielder who seems to be on the fast track to becoming an AFL superstar.
Jack's ferocious tackling was evidenced throughout the regular season and in the finals campaign, when he introduced Carlton skipper Chris Judd to the ANZ Stadium turf in uncompromising fashion.
Jack, 23, led the club in tackles in 2010, was ranked third overall for kicks, fourth for disposals, third for contested possessions and second for inside 50s. He also booted 21 goals.
Mumford polled outstandingly considering he missed two games after being suspended for tangling with former teammate Gary Ablett. The big man also missed a week with a knee injury.
Alongside his third placing in the overall count, Kennedy earned the Paul Roos Award for best player in the finals series.
In other news on the night, the Swans staged a tribute for retiring coach Paul Roos and captain Brett Kirk.
Kirk marked the end of an era by imploring his clubmates to "continue to take care of and look after each other" before embracing Roos and declaring as Adam Goodes handed him the AFLPA Captain of the Year Award that "it's all about the love."
