instruction: Why are so many NFL coaches related to each other?
response: The most common path towards acquiring a coaching job in the NFL is through connections to family or friends who are already employed by an NFL franchise in a coaching or playing capacity. Historically, people have criticized the league for not employing steeper measures to reduce nepotism among coaching staffs, however, there is little the league can do to prevent this as many coaches prefer to employ staff they are already familiar with.
