We absolutely, 100%, no question or debate, do not need the boosters to be dictating what decisions we make for hires. They are absolutely allowed to put an opinion in and Batt has to listen, but he can't be forced to agree or there was no point in hiring him. Maybe excessive hyperbole, but it's one of those situations where if you give an inch they could end up taking a mile. This may not be what is happening, but it is a theoretical possibility based on the info (that may or may not be accurate) we have.
What I mean by poisoned the well is that if they really are being super overbearing in trying to get Key the job, then Batt is in a position where it becomes harder to hire him regardless of whatever other merits the choice may have.
