Antonio Pierce, a player's coach a leader of men liked by the players in Vegas had been a player in the NFL had coached at all levels etc etc etc.
Was an awful head coach.
Where have we seen this before?
Being a good coach is 90 percent a media driven narrative. Your destiny in the NFL is about who your past connections are who currently have a job in the NFL and whether or not someone in the media likes you enough to label you a good coach.
For a prospective coach looking for a job? Sure, I can buy that. That applies to Chicago's situation now but I don't think it applies to where the Raiders were as a franchise, because they didn't have a QB worth a dime. They are starting over, possibly with Shadeur Sanders at QB (Which I personally want to see so very badly). With regard to Antonio Pierce, it was not about being a leader of men, it was about not giving the future of a rookie QB to a coach that already looks like he doesn't have what it takes to elevate the program. I think that is where it compares well to Chicago, in that the team absolutely should have started over with a new coach this past season.
But being a good coach while you are an HC is about building a program and being in charge of situational football. Not every HC remains a playcaller and has to delegate responsibility, but every HC needs to be on top of using time outs, challenging a ruling, rotating players, going for it on 4th, etc. What we as fans call "a leader of men" I think comes down to how a team's identity becomes shaped by its HC, which is part of building a program that repeats success. Andy Reid, Mike Tomlin, Sean McVay, and John Harbaugh all have this quality, and I do not doubt that Dan Campbell has an honest chance at being the next on the list.
