Last thing on BJ..... there is a reason it is taking a second round of interviews (from last year) for him to figure out how best to interview for a HC position. He did not win anybody over last year. This year, by trial and error he will finally land a HC'ing gig. This says something though - about him. As someone who has served in a role where I hired and fired people before, there are guys that "have it"..... and they have that "it" the moment they walk through the door. They are dynamic, confident, well spoken and assertive. If is it is taking BJ a while to learn those traits, then that means it is not natural to him.
Keep in mind, this is not GB, SF, Baltimore, KC or NE of yesteryear -- well run organizations that can have a guy come in and focus on his narrow lane. This is a mess of an organization. This job needs a culture changer.... a smart guy who will fight for what he wants.
I get what you are saying, but despite these rumors from unknown sources, there are the stories that he has basically had 2 job offers in hand the past couple of years and chose to stay as an OC as the better career move for him at that point in time. Last year it was the Washington job and the year before it was the Carolina job if I remember right. At the very least, there were strong indications he could have had those jobs if he wanted them. Obviously the teams will never admit they got anyone but their first choice.
Also, it is basically standard practice in the NFL for their to be an initial round of interviews and then a 2nd set of interviews with a smaller candidate group before a team makes a final decision. So, how the hell is him doing a second round of interviews somehow a bad thing? It means there was interest by the teams. Literally the NFL rules for the HC interview process lay out how teams are allowed to arrange for 1st and 2nd interviews. It's an expected thing.
And if that is not enough, the NFL also changed some of the rules regarding interviews with coaches whose teams are still in the playoffs. If I remember right, that first interview can only be virtual now. That has to have an effect on how well you can really connect with a person.
Also, I don't think there has been much mention of why he didn't interview well. Was it actually a lack of ability to command a room? Was it his preparation for the job? Was he too wordy? Or the opposite, were his answers too short? We have no way of knowing the exact reason for any negative feedback. And depending on which variables were actually the issue, some are more correctable than others.
For example, there has been a knock on Johnson that he may not have as many league wide connections. So, his preparation on how he would actually build up his coaching staff may have been unsatisfactory to some teams. I have read articles before that talked about HC candidates knowing their 1st or 2nd choices for each staff position, but when asked if they can't get those, then what? And not always having that answer. That can be correctable and these 'extra' years as an OC can give him time to make more league wide connections to build a coaching staff when/if he does eventually take a HC position.
