At the end of 2011, even though Collingwood lost the granny, Collingwood still had all of Pendlebury, Swan, Cloke, Reid, Shaw (a young Sidebottom and Beams) all in there prime of there careers, from the 2011 team off the top of my head the only players who were done and dusted were Didak, Tarrant, Johnson, Ball, Jolly and Leon Davis.
Such a good team gutted by a man who has shown to have no idea what he's doing.
From the 2010 Premiership and 2011 GF sides:
Leigh Brown was done at the end of 2011. Chris Tarrant was done at the end of 2012. Alan Didak, Andrew Krakouer, Ben Johnson and Darren Jolly were done at the end of 2013. Luke Ball and Nick Maxwell were done at the end of 2014. Brent Macaffer, Dane Swan and Alan Toovey were done at the end of 2016. All that played on after 2011 had significant dips in form or ongoing injuries woes before retirement. That's 11 players, half the team, who simply came to the end of their footy life, nothing to do with Buckley. None played elsewhere after Collingwood.
Chris Dawes and Heritier Lumumba are out of the league, Dale Thomas has been a shadow of his former self at Carlton (yesterday was probably his best game since 2011), and Dayne Beams (despite a B&F and the captaincy and Brisbane), Sharrod Wellingham and Travis Cloke so far have spent half the time at their new clubs injured. Heath Shaw (AA last year) has really been the only great success of players that were supposedly "pushed out in their prime". That makes another 7 players, who the Pies were all well compensated for in return. Would the side be any better now and going forward (considering the players/picks they got in return), if they had clung to them? I doubt it.
Jarryd Blair, Alex Fasolo, Tyson Goldsack, Scott Pendlebury, Ben Reid and Steele Sidebottom all remain at Collingwood.
This all is a pretty standard turnover for any club in a 5-6 period, by the way. A refresh was certainly in order by the end of 2013 (which is when it began being instigated), but people don't seem to get it, and think the Pies just gave away stars while they were still fit and performing, which wasn't the case at all.
