Murray moves in next to captain Scott Pendlebury and will have the chance to get up close and personal with one of the game’s greats.
The number has a spotty record at Collingwood, with only four players playing more than 100 games in it (Ron Kingston, Harry Chesswas, Jack Green and Craig Stewart).
The 20-year-old was the third-last selection in the 2015 rookie draft and spent two-years on Sydney’s list but failed to make a senior appearance for the Swans.
Murray played his first season as a forward but he shone after a shift to defence this year, earning selection in the 2017 NEAFL team of the year averaging 22 possessions, six score involvements and 3.5 inside 50s from 18 games.
Last week, he was traded to Collingwood for their 2018 second-round pick, and brought Sydney’s pick no. 70 and their 2018 third-round pick with him.
