Jerry Jones is at it again.

The Dallas Cowboys suffered an embarrassing 19-3 loss at home last Sunday in their season opener to the Tampa Bay Buccaneers. On top of that, quarterback Dak Prescott suffered an injury to the thumb on his throwing hand and will be out 6-8 weeks after successful surgery on Monday.

This immediately puts the Cowboys' hopes of returning to the postseason in jeopardy, but don't tell team owner Jerry Jones that. Forever the salesman, he is giving Cowboys fans a ton of optimism.

"One of the things that has stood me about football, and I'm comparing to the things that we all do every day away from the football is that it can be looking very dark, dark for you and then it can reverse on you in an instant," Jones said, via the Dallas Morning News. "It can go positive in an instant after you've got — we've got a lot of football. We've got a lot of really top football players. And we got an outstanding group that's coaching them up in my view. … You can think negatively and everybody does and that's normal. But, boy, we got a lot of positive things we can do. I have seen it just hopeless and walk out there and David slay the giant. I've seen it done."

Oh, Jerry.

The Cowboys' offense was putrid with Prescott against the Buccaneers. Now, backup Cooper Rush is being asked to put a bandaid on things until he returns. However, with a depleted receiving corp that looked lost in the wind when it came to running routes and catching passes in Week 1, that's going to be a struggle and would have been for Prescott going forward even if he was healthy.

It's no secret that the Cowboys had issues on their offensive line entering the season, albeit self-imposed due to their lack of diligence in the offseason although they signed veteran Jason Peters at the last minute after Tyron Smith tore his hamstring. Unfortunately for the Cowboys, guard Connor McGovern suffered a high ankle sprain against the Buccaneers and will miss 2-4 weeks, causing the Cowboys to have to hurry and find the right combination for their offensive line before taking on the Cincinnati Bengals on Sunday.

Defensively, the Cowboys looked good even in a loss against the Buccaneers. The problem that they will have going forward is that offensively the Cowboys will struggle and that will force a lot of short drives which will put their defense on the field a lot. Regardless of how good a defense is, and the Cowboys have a good one, the more they have to be on the field they will eventually give up plays, and seeing as scoring points will more than likely be a major issue for the Cowboys for a while, it doesn't give a lot of hope for good things to happen.

There's nothing wrong with thinking positive, at all. Jones could probably sell water to a whale if he had to. But, the reality is that the Cowboys have a tough stretch of football ahead, and if you're buying what Jones is selling, buyer's remorse will likely follow, and soon.
