After reading a few articles yesterday about this process, its looking more and more like Shanahan was asked what it would take to get him hired and he said get rid of Vinny.

Many of the other GM's that saw and talked to Vinny at the NFL meetings late last week said Vinny was not aware of any changes. He was scouting and preparing for the draft. That does not sound like a guy getting ready to quit.
The fact that he went to the meetings is a sign that he was out of the loop.
Plus throw his childish disrespectful slap at Zorn during his exit speech and that is a sign of a guy that is not happy about this move.
