"From earlist days of the NFL to the present day, head coaches have loomed larger than life. Here are several coaches with prominent coaching trees:"
"Because coaches challenge one another each day in practice, the staff that you are on can indicate future success. Here are several teams with multiple successful head coaches:"
"Similar to a family tree, a coaching tree describes an NFL Head Coach's football lineage through multiple generations. Assistant coaches learn under one or more head coaches before being promoted to a head coach themselves, becoming a new branch of the tree. Teams searching for a new head coach often look to the coaching trees of previous champions in an attempt to find a successful coach for themselves. Unfortunately, though this is a common strategy in the NFL, not every winning coach succeeds in producing successful assistants. The challenge, then, for front office staff is to find the coaching trees with the strongest branches for their next head coaching hire."
