Harvard Business Review might not think Leeds United worthy of a case study but it has done the next best thing and looked at the impact of stars on Wall Street. Harvard found that stars rarely delivered the expected goods when they moved from one firm to another for two reasons. First, they were not really stars anyway, in so far that much of their success was because they were in the right firm with the right people-at the right time. Second, having been hired for a ridiculous amount, they felt obliged to live up to their billing and alienated their new colleagues. They were like an organ transplant - healthy enough but rejected by the new body.
