DOES the upheaval of losing a coach partway through a season galvanise or tear apart a playing group? History, as always, tells an interesting tale.

Following the premature departure of Stuart Dew at Gold Coast, attention quickly turned to Steven King's first game in charge of the Suns, against St Kilda on Saturday afternoon.

In the past decade, 14 senior coaches have left their club partway through a season, with teams holding a 6-8 record in their first game with a new man at the helm.

While the raw numbers offer no real insight for Saturday's clash against the Saints, a deeper dive indicates a new coach can lead to an immediate lift.

In most circumstances, a senior coach has departed after a string of poor performances and heavy defeats. The fact these struggling teams, over the past decade, have a win percentage of 43 per cent the following week suggests on-field improvement.

Even teams that have lost their first game of a new era have often been much more competitive than they had been previously. This year, only a bizarre interchange infringement cost North Melbourne a rare win over Sydney just days after Alastair Clarkson stepped away for personal reasons amid a seven-match losing streak.

In 2013, Melbourne lost 10 of its first 11 games by an average margin of 82 points under Mark Neeld, with the only win coming against the lowly Greater Western Sydney. The Demons' first game under interim Neil Craig was a loss to St Kilda by a relatively respectful 35 points before they secured a breakthrough win over the Bulldogs the following week.

In 2015, Essendon lost to Gold Coast by just two points in its first match after James Hird resigned as senior coach. Coming on the back of a five-match losing streak, including two losses by more than 80 points, such a narrow defeat – Jake Carlisle missed a late shot on goal that would have won the game – represented an uptick in performance.

Of the six teams to have won their first game under a new coach, three of them - North Melbourne in 2022 (15 games) as well as Carlton (seven games) and St Kilda (four games) in 2019 - broke long losing streaks.

But there are no guarantees a change of coach will bring a change of fortunes straight away. Fremantle in 2019 (after the departure of Ross Lyon), Gold Coast in 2017 (Rodney Eade) and Carlton in 2015 (Mick Malthouse) all lost their first game under an interim coach by more than seven goals.
