TI #026: What Actually Gets Teams Promoted?
Timeless Insights #026
Promotion changes everything.
It changes budgets, recruitment power, staff structures, player markets, expectations, and sometimes the entire trajectory of a club. That is why second-tier football is such an interesting space for analytics: the margins are brutal, the incentives are enormous, and the difference between “nearly” and “up” can reshape a club for years.
This week’s paper looks directly at that question:
Which technical performance indicators actually increase the chances of promotion to the elite leagues?
The study analysed professional second divisions in England, Germany, and France across five seasons, using 11,032 team-match observations and logistic regression models to identify which defensive, set-piece, and passing indicators were linked with promotion.
And the result is not simply “better teams attack more” or “promoted teams defend better.”
It is more specific than that.
One of the most useful ideas in the paper is that some metrics describe control, while others describe survival.
A team making lots of clearances, blocks, and goalkeeper saves may look busy, committed, and defensively active. But in this study, those actions were not signs of promotion-level strength. They were signs that the team was spending too much time under pressure.
In football analysis, we often talk about defensive volume as if more defensive actions automatically mean more defensive quality. More tackles, more blocks, more saves, more clearances. But those numbers can also tell a very different story: that the opponent is reaching your box too often, forcing your goalkeeper into the game too often, and making your defensive unit solve problems too late.
The study found exactly this pattern. Teams whose goalkeepers were frequently making saves, and whose outfield players were regularly clearing the ball or blocking opponent actions, had significantly lower chances of promotion.
That is a useful reminder for analysts and coaches: not all defensive activity is defensive success.
Sometimes the best defensive teams are not the ones doing the most defending. They are the ones preventing the game from arriving in those zones in the first place.
And that takes us to the more interesting part of the paper.
Because promotion, at least in this study, was not only about avoiding defensive overload. It was also about having clear ways to create high-value attacking moments.
Not vague attacking intent. Not possession for its own sake. Not just “being proactive.”
The signals that mattered were more direct: penetrative passing, chance creation, and set-piece execution.
The question, then, becomes much more practical:
Can we separate teams that merely look active from teams that repeatedly generate promotion-level advantages?
