I'm afraid that I have to agree with Mr TD here. Beanie is very much a legitate candidate. Just because he's not as good as the other candidates does not discount him. Just because JR hired a consultant to find someone does not discount him. You said at the very beginning that this was about candidates who have been mentioned, and he has certainly been mentioned. I don't think he is a good candidate, and I don't think he will get the job, but I also don't think for a second that he has a zero chance of staying in the role.
He's been mentioned, by one guy, that guy being Pat Yasinskas. The same guy who declared that Mike McCoy was a dead solid lock for the Panthers OC spot right before it was handed to Jeff Davidson. Where did he hear that? From Mike McCoy's agent.
And regarding Beane, Yasinskas only mentioned it as "what he thinks". He had no source at all. Though if he does, true to form, it's probably Beane's agent.
The other guy at the national level who was asked about Beane was Adam Caplan, who completely discounted the idea. He cited discussions with league sources who said no one was taking Beane seriously as a candidate.
Beane does not have a shot.
