The total approach of a team's philosophy shifts when a head coaching change occurs.
Just before the New Year, we saw seven NFL teams—which is almost 25 percent of the league—fire its head coach.
Interestingly enough, there is much disparity between the coaches' overall resumes and how their 2012 season's panned out. The Philadelphia Eagles were led by Andy Reid from 1999 through this season.
He was then let go by the Eagles, per Vaughn Johnson of Philly.com, and the franchise is looking elsewhere for the first time since the 20th century. On the contrary, we'll also see some teams who have made multiple changes during that same span.
As a result, the future landscapes for each team vary across pro football's spectrum.
