Is knowledge leverage librarians' task?

Although I am agree with most parts of .">Ferguson's paper it is hard to accept some other points. For example:

The more senior "knowledge-enabling" tasks...require a level of leverage that very few librarians enjoy, although many may aspire to it.Some include a strategic information management role that includes development of an organization's IT infrastructure...
or
Knowledge leverage needs to take place in parts of the organization never reached by librarians.
or
It seems to me, therefore, that many of the knowledge-enabling tasks are best effected by the Human Resources division in an organization. We are talking about significant evolutionary developments in organizational culture.

We should ask ourselves why librarians can't reach knowledge leverage?
If library and information professionals expand their skills are there better opportunities for them on knowledge management?
I think librarians should be part of a team for IT infrastructure because as Dorabjee (2004) states: IT staff tended to focused on the technical side, ignoring the more fundamental information management requirements.
