At the end of their runs, the greatest offenses in NFL history have been a little like Tiger Woods in 2008: dominant for a decade and seemingly poised for more before falling off the proverbial cliff.
The New England Patriots' offense is currently in the midst of a decade-long run on par with those of some of the most dominant units in NFL history. With Tom Brady coming off a Super Bowl in which he showed no signs of slippage, the Patriots look primed for another elite output in 2015. But a strong gravitational pull has reined in previous dominant offenses at about this time in their runs, even when those units have returned great quarterbacks. Is this offense -- and the game itself -- different enough from its predecessors to make the Patriots a good bet to stay airborne for a while longer?
