If you are the head coach of an NFL football team it means you are one of the best in the world at what you do. There are only 32 teams and 32 head coaching spots. It is one of the most prestigious jobs in professional sports and it comes with tremendous rewards if you succeed. On the other hand, if you screw it up, there is a long line of people waiting to take your job.
Head coaches may be in charge, but it is a high-stress position, and they often get the blame when things go wrong.
