I don't know how accurate the assessment is, and I don't know what kind of jerk they might be talking about, but I have worked with brilliant jerks before, and it was a relief when they finally moved on. They did amazing things, but the atmosphere became increasingly toxic, and morale, quality, and productivity all went up when they left. Having a "Brilliant Jerk" on your team sounds useful and manageable, but in my experience it's not. Again, I don't know if this was an accurate assessment, but if you want to have a brilliant jerk, all I can say is that you should be careful what you wish for.
