Star players make better basketball coaches, according to research by scholars at the University of Warwick and Cornell University. The research is further evidence that experts in their field rather than generalists typically make the best leaders in organisations.
Using data from 15,000 basketball games between 1996 and 2004, the authors learned that the US’s premier basketball teams in the NBA (National Basketball Association) tend to win more games if led by coaches who were star players or if they had long playing careers, controlling for other factors that affect team performance. That upholds the authors’ hypothesis that, across many kinds of industry, it is experts in their field who typically make the best leaders.
In the current US NBA finals, the Lakers’ coach, Phil Jackson, is tied with the Celtics’ legendary Red Auerbach for the most championships as a head coach (nine) and has the second best career regular-season winning percentage (0.700) of all time. While he was never an NBA allstar player, he had a long NBA playing career (12 seasons), a mark of distinction, since only the best players in the world are invited to play in the NBA. Doc Rivers, the Celtics’ coach, was an NBA allstar player, had a 13 year NBA playing career, and led the Celtics to this year’s best record in the NBA, though with some help from the addition of two star players (Ray Allen and Kevin Garnett) to the roster.
Former NBA allstar players such as Danny Ainge, Larry Bird, Maurice Cheeks, and Jerry Sloan each had winning percentages better than 0.600 as NBA head coaches during the period the authors studied.
The research report entitled "Why Do Leaders Matter? The Role of Expert Knowledge," says the beneficial impact of a star-player-turned-coach is discernible during the coach’s first 12 months with the team.
While not all former all-star players had winning records as head coaches, the authors found that on average, "having a former all-star player as your coach is worth about six extra places up the NBA league table," said Larry Kahn, Professor of labor economics and collective bargaining, at Cornell’s ILR School. "We were surprised at the strength of the statistical evidence."
Kahn’s colleagues on the research are Dr Amanda Goodall, a management scholar at the University of Warwick’s Business School in the United Kingdom, and Professor Andrew Oswald, an economist at the University of Warwick. Both are visiting fellows at Cornell.
Warwick Business School’s Dr Goodall said, "Forget charisma. Forget the airport-book stuff. Our results are consistent with the common sense idea that organizations need to be led by people with deep expert knowledge of the core business."
The authors speculate that a deeper understanding of basketball gives top-players-turned-coaches a significant edge over other coaches. This may come through better tactics or increased credibility with players, they said.
Coaches who never played in the NBA have never made the playoffs in the coach’s first year with the team, compared to about half of the teams taken over by a former NBA player, according to the report.
The authors’ work began as an attempt to understand leadership in general. The NBA is a natural laboratory for testing, they said, because of data availability, small team size and the comparative simplicity of the professional basketball industry.
The authors believe that their results are likely to generalise to many economic and organisational settings. Experts tend to make the best leaders, they said.
