Every season, a new crop of coaches enter the NFL, and a few others hop around from one team to another in hopes of new beginnings.
Only two first-year coaches have ever won the Super Bowl, and in general they have bumpy opening campaigns.
Some teams reach into their own staff to find a coach, some look to other teams and a few may even dip into the college ranks, or find a coach who is out of work.
Prior to the 2011 NFL season, eight teams had different men at the helm than on opening day of 2008. Only one of these coaches had been an NFL head coach previously.
Among these coaches, some rose to the challenge, whilst other withered under the pressure.
I will rank how these eight men performed.
Note: Interim Coaches hired in 2010 and maintained (Garrett and Frazier) will be counted, but those hired in mid-2011 will not (Mel Tucker, Romeo Crennel, etc)
