I would say the Cowboys are truly a mass media creation- a historic franchise with a national following. Always rank highly in merchandise sales. It benefits the major networks (Fox, CBS, NFLN, etc...) when the Cowboys are in the national discussion. Therefore, the players are always hyped collectively overrated.
I wish I agreed that they are close. The record pretty clearly shows that this team feasts on a weak division and fades significantly during the stretch drive, particularly against tough competition.
I'm a Red Sox fan as well so I know the narrative can always change, but right now they look a ways away from truly being a Super Bowl contender. My feeling all season was they needed to win a playoff game to show their legitimacy. It would be no shame to have won yesterday and then lost on the road at Tampa Bay. Losing yesterday, particularly in the fashion they did shows there is no difference between this team and other playoff failures- they played poorly, and seemed mentally unprepared (as well, physically).
They will play a first place schedule next near and the division can't be worse. This team will be 10-7 or 9-8 next year, with marginal playoff aspirations yet again. I see more of the same, no indication that they have learned or are better off from yesterday. Instead, the press conferences doubled down on stupidity- not a way to get better.
Ultimately, it rests on JJ, and he's not going anywhere, nor are there any indications of any self-awareness on his part. The definition of insanity is doing the same thing over and over and expecting a different result- the Cowboys are the sports embodiment of that maxim.
