I don't know about that. It'd be really easy for a credulous person to read that article and think "oh, some of my execs aren't world class yet. Guess I'd better replace them."
Yeah, once you've lost the respect of your reports (or failed to ever gain it) you can't do your job as a manager or executive, period. But that doesn't mean that great execs are born rather than made or that nobody should put any effort into developing a great manager into a new exec or a new exec into a great one, which the article seems to fallaciously suggest.
