But the point is he can't negotiate or interview without the risk of being in violation of that contract, so he'd almost certainly have to be assured of the job before getting too involved, which I believe would be far too difficult when it's a HC and GM whose jobs are on the line and want to be sure they are getting the right guy. A guy like Parcells can get away with it because everybody knows what they bring to the table. A QB coach getting a promotion to OC without actually having a well known track record is a tricky situation. GB denying permission does, in effect, end his candidacy. If this was a position coach that the GM worked with before, and everybody was familiar with, it would only be a formality they could easily get around with some sort of buyout. But in this case, it has an impact.
