It is as far as I'm concerned. At least insofar as possible playoff hopes given the divisional impact of starting the season three full games behind NY, with a home loss already on the books against Dallas.
As far as the big picture view of the team, and Kirk's development, at 0-3 I would shift my focus from the playoff implications in 2016 to the hope the team shows clear signs of getting its shit together before the end of the year, and letting us head into 2017 at least knowing we're moving forward with Gruden and Cousins and not possibly facing The Big Flush and starting all over again.
