Coaching Tenure Outlasts No Analytical Programme
Average head coach tenure runs about two years across major professional leagues, which means any programme requiring behavioural change outlasts whoever agreed to it and starts again with a successor who has their own convictions. Analytical input measurably changes around 23% of coaching decisions. Vendors selling tactical insight are asking somebody with two years of security to trust a model over the judgement that got them the position in the first place. Programmes surviving a coaching change are those an executive owns rather than those a manager championed personally. Conviction expires.
