The Long View

Two Years or Out

Four in ten head-coaching hires are gone within two seasons, the interim year is a lost year, and the ten-year tenure you envy is a survivor, not a strategy.

Every hiring cycle gets narrated as a fresh start, and the record reads more like a schedule. Of the 201 head-coaching stints that began between 2000 and 2023, 81 lasted two seasons or fewer, four in ten, and the quick-exit rate cleared one in four in every hiring class but one. The league does not really give coaches five-year plans. It gives them two Decembers.

The interim season is a lost season

When a team fires its coach midseason, the year is already over. The 43 team-seasons since 1999 that used two or more head coaches won 31.9 percent of their games, about 18 points under a coin flip, and finished under .500 every single time one existed. Read that with the selection arrow pointing the right way: coaches get fired in-season because the team is losing, so this is the profile of a team bad enough to fire its coach, not the cost of the firing itself. Either way, the interim label and a playoff push have never shared a season in this record.

Tenure is a trophy, not a lever

Teams whose head coach is in year five or beyond win at about a .55 clip; teams with a first-year coach win at about .42, a gap that has pointed the same way in all but one season since 2004. None of that means keeping a coach longer would raise your win rate. The causality mostly runs the other way, because winning is what keeps the job. Year-five coaches are the survivors of four consecutive Decembers of exactly the filter this article opened with. Tenure is the effect of winning at least as much as its cause.

Long tenures do not create winning. Winning creates long tenures, and the carousel recycles everyone else.

The quarter-century club

The churn is the building, not the coaching staff. Of the 3,421 players whose first active-roster season came between 2003 and 2011, just 51, about 1.5 percent, ever reached a fifteenth season on an active roster. In every entry class, more than 19 players in 20 fell short. The fifteen-year veteran and the ten-year head coach are the same kind of object: a survivor so rare that our intuition, built from watching only the survivors, badly overestimates how long anyone lasts.

How to use it: when your team hires a coach, set the clock at two years, because the league will. When an interim takes over, stop evaluating the season and start evaluating the draft position. And when a pundit credits a franchise's patience for its dynasty, remember you are hearing the survivor's story told backwards.
