Do you have to be crazy to be disruptive?

Not long after Steve Jobs returned to Apple, the iconic “The Crazy Ones” commercial aired as part of the larger Think Different campaign. This is a variation of that commercial that never aired, with Steve Jobs himself narrating.

 Here's to the crazy ones, the misfits, the rebels, the troublemakers, the round pegs in the square holes... the ones who see things differently -- they're not fond of rules... You can quote them, disagree with them, glorify or vilify them, but the only thing you can't do is ignore them because they change things... they push the human race forward, and while some may see them as the crazy ones, we see genius, because the ones who are crazy enough to think that they can change the world, are the ones who do.

But, do you have to be crazy to be disruptive?  Can disruption be systematic and planned, strategized and organized?  Are the elements of disruptive innovation well enough known to be written down and followed, like a recipe for an omelet?

Where is the middle ground between planned innovation and crazy innovation that can lead to disruptive innovation at a frequency greater than chance?  Does disruptive innovation require the type of person described by Steve Jobs in the above quote, or can a person with the ability to understand and define technology trends have the insight that recognizes when some of those trends, when integrated, provides an opportunity to do something no one has done before and create a disruptive innovation?

I would like to think the latter is true and not everyone who creates disruptive innovations has to be crazy.  What do you think?
