The 2013 NFL season promises to be one of infinite possibilities.  Whether you are a peripheral fan, an obsessed fan, or just in it for the fantasy value, it will be interesting.

With eight new head coaches anything goes. 

Which head coach holds the most promise?  Which head coach will see the pink slip at the end of the season? Nothing is guaranteed in the NFL except that failure is unacceptable (unless of course you are Rex Ryan).

So which team did the best job in acquiring a coach?  They can't all be good and very few will be great. 

How will they be judged here?  By the potential of being one of the few.
