My latest story for Wired Playbook discusses recent research from a group that analyzed 46 seasons of professional German soccer league data to determine that firing a coach mid-season — a tactic clubhouses use to jump-start a fledgling team — has absolutely no effect on the squad’s performance.
So, to really compare apples to apples and provide a clearer picture of what effect a new coach has on a losing team, Heuer thought it better to identify suitable control groups — teams that had bad luck, but stuck it out with their current coach for the rest of the season — and compare them to teams that handed their coach a pink slip when times got tough.
As they suspected, there was absolutely no difference between the teams that fired or retained their coach, as all teams that experienced an early period of bad luck showed improvement later in the season. But pride is a formidable enemy, and the data consistently showed that in many cases, a team decided to prematurely give their coach the boot after they took a beating on two consecutive games.
