There's that enormous ego I was talking about. See unlike a lot of fans, those in charge don't see things as just black and white. They see and understand there can be and usually are many many things that are not the fault of the coach for not reaching a championship game. If the coach is well like and respected by the players and they have a good locker room and the team isn't stuck in continual losing seasons and there are signs that the team could get things done then there's not going to be the knee jerk response that fans have. If Jerry's or Stephen's door is constantly open by players complaining about Garrett then they would put that win or else leash on him and nobody knows for sure but I doubt that is the case. Lastly if making those decisions were so easy and just black and white then at least one of these ultra ego users here that think they know all there is to know about the NFL would have been hired by some NFL team but unfortunately for those users with their ultra egos, teams look for at least some previous experience other than sitting on one's couch.
