So what really is the argument here? I'm really curious. Is your point that we have reason to be concerned? I can go along with that, but that point could be made for 31 teams.
Take Seattle, for instance. If I am a Seattle fan, I am a little concerned that despite all of the Seahwaks starters playing the first half (and into the 3rd quarter) versus a mixture of starters for the Cowboys, we still went into the half tied. That's against the backup QB for all but 3 plays. That's without the services of Dez and Tyrone Crawford for the entire game. That's against Zeke for only two series out of the entire half. Anyone who was watching and watching intently, knows if the Cowboys don't start pulling starter after starter starting at the end of the first quarter, the scoreboard is likely in the Cowboys favor.
The fact is, if you simply google every team name in the league along with "preseason" you will find articles lamenting weaknesses. They are everywhere for every team. That was the reason I posted the video in the first place. Not to say that the Giants will be a layup (though they very well might be) but mostly my intent was to point out that the Giants have their own problems to contend with during game 1. And you won't have to look very long to find that nugget about every team on the Cowboys schedule. And the further removed we get from game 1, the more issues that will come up across the league which will change the face of competition from week to week.
My contention is, Dak is good enough. Too soon to say "great." Too soon to order his Hall of Fame bust. But with that OL, those WR/TE/RB, Dak doesn't have to put the team on his back and go win games. All he has to do is get the ball to his playmakers...and there are plenty...more than what most teams can boast So my point is, I think the Cowboys will be just fine in Romo's absence. I know that is crazy to say with 2015 so close in the rearview...but I think Dak is special. By no means a finished product, but he does have that certain "it" factor that will be enough to overcome most of the teams the Cowboys face this year. Of course, as always, that is just my opinion.
