Why would Fassel subject himself to this? Why would any coach, at this point, subject themselves to this?
Every coach in the NFL knows the shape this team is in, and they know they have no chance of succeeding until Al Davis takes a big step back away from the team, and lets a true GM or possibly a GM/Head Coach take this thing over.
You can't force the guy to do anything, but if everyone would just remove themselves from consideration of being associated with the team, he would have to get the hint. If he still didn't, at least the league would then have a solid case for stepping in and forcing their hand on the organization.
