Collingwood Football Club After months of speculation, Buckley signed a 5-year deal with the
Collingwood Football Club and in July 2009, Collingwood Football Club President
Eddie McGuire produced a succession plan in which senior coach Malthouse was to hand over the coaching reins to club legend and assistant coach Buckley at the end of the 2011 season. He was the assistant coach under senior coach Malthouse for the
2010 season, including being part of the club's coaching panel in the club's
2010 Premiership victory, and in the
2011 season; he then became senior coach in 2012, Collingwood under Buckley began the
2012 season shakily, losing to Hawthorn in round 1 and being thrashed by Carlton in Round 3. However, they recovered to win their next ten matches and finish the home-and-away season in fourth place with a record of 16–6. They were defeated by Hawthorn in the Qualifying Final before bouncing back to defeat West Coast in the semi-final. However, they lost comfortably to eventual premier Sydney in the Preliminary Final at ANZ Stadium to bring an end to the 2012 season. 2013 started poorly for the Magpies under Buckley, slumping to a 5–4 record after 9 games. They couldn't quite find the consistency of previous seasons and finished the year in sixth place with a 14–8 record. They played Port Adelaide in their Elimination Final at the MCG and slumped to a shock 24-point loss, which caused Buckley to call into question the club's culture. however, Collingwood produced a poor performance in round 1 and lost to 2013 grand finalists Fremantle by 70 points. They ended up missing the finals to finish 12th at the end of the 2014 season partly due to an injury crisis. The Magpies' 2016 season commenced with a heavy 80-point loss at the hands of Sydney and what would be a career-ending injury for
Dane Swan. Collingwood rallied the following week, producing an extraordinary 1-point comeback win over Richmond. But the season was again one of failure overall, with injuries to senior players and poor form of others being a factor. They ended 12th on the ladder again with a 9–13 record. Buckley took some heart from a strong finish to the season. Many assumed Buckley would be sacked, but Collingwood honoured his contract extension and Buckley made himself personally accountable for the side's upcoming 2017 season. Poor performance continued into early 2017, with the Magpies losing four of the first five games and being 5–10 after fifteen. Again Collingwood finished the season strongly, with four wins and a draw from the final seven games. They finished 13th on the ladder with a 9–12–1 record. In the
2018 season, despite another injury crisis, Buckley still managed to coach Collingwood to their first Grand Final since 2011.
Collingwood lost that Grand Final to the
West Coast Eagles by a margin of 5 points with the final score West Coast 11.13 (79) to Collingwood 11.8 (74). This form continued into 2019, Collingwood finished fourth on the ladder with a 15–7 record and defeated top-of-the-ladder Geelong in the first week of the finals. But the Pies missed the Grand Final following a heart-breaking 4-point loss to the GWS Giants in the Preliminary Final. Through the
COVID-19-affected
2020 season Collingwood were forced into numerous interstate hubs. The club was fined after Buckley and assistant coach
Brenton Sanderson breached COVID protocols during their stay in Western Australia. Collingwood produced a patchy year in terms of form, finishing 8th on the ladder with a 9–7–1 record. The Pies managed a stirring 1-point win over the Eagles in Perth in week 1 of the finals, but were eliminated the following week by Geelong. Buckley supported Collingwood following a tumultuous 2020 trade period which saw three senior players, including Treloar, depart for a modest compensation. After a poor start to the
2021 AFL season, calls began to rise for Buckley to be sacked. The resignation of McGuire from his position as club president earlier in the year was viewed as potentially putting Buckley's position in danger, since he had been one of Buckley's staunchest supporters. On 9 June 2021, Buckley announced that he would step down as senior coach, effective after the Round 13, 2021
Queen's Birthday match against . Collingwood won the match by 17 points; it was their fourth win of the season. Buckley was replaced by assistant coach
Robert Harvey as caretaker senior coach of the Collingwood Football Club for the rest of the 2021 season.
Geelong Football Club After losing the Melbourne head coaching position to
Steven King, Buckley joined
Geelong for the 2026 season as an assistant coach. He also continued to work as an analyst at
