I'm not sure I would share that characterization. There is an important line to be drawn between oversight and management. There is always a challenge for boards to ensure that they're not running the business, yet they're challenging the decisions of management. That's a unique role and position to occupy, and you need the right kind of competencies and strengths to be able to do that, with the assurance that you can, while not taking over.
I would characterize it a little differently. I'm not concerned that they're trying to abdicate and are just holding their positions without doing anything, but if you weaken a number of people who are on a board to the point that it's very difficult to establish committees and have quorum, all the responsibility lands on a very few, and it becomes overwhelming. To what you are observing, you may, in many cases, see a situation in which a board has vacancies, or individuals who are uncertain of their future, which leaves a very small number to handle the whole thing, and it's just too much for them.
