The Cowboys have the largest valuation of any NFL team, they in tops in terms of merchandise and TV rankings but the Cowboys are not the NFL's version of the Yankees.
The Cowboys have not won a Divisional or Conference Championship playoff game since 1995. Their playoff record since '95 is 3-8.
Prior to this season they've had one winning record in the regular season since 2009. Since the last SB in '95 they've had a 162-158 regular season winning record.
Cowboys are one of the league's premier teams but they're not leaps and bounds better than New England, Pittsburgh, KC, Denver, Green Bay, Seattle, Giants from the perspective of fan support, TV audience ... "America's Team"? Go ahead and believe that but only their fans and their media shrills really believe it!
