The Dallas Cowboys are their own biggest hurdle to jump

The Dallas Cowboys are primed to have a very good season. They themselves are one of the biggest hurdles they will have to jump to make it possible.

With Dak Prescott heading into his fourth full season as the starting quarterback of the Dallas Cowboys, his team is primed to have a huge season. They should be getting everyone, including their offensive line, back to as close to full health as they have been over the past few seasons.

They have also had a full offseason to work with some of the younger guys and new additions that were key players for them during last season. Jason Witten is back from retirement and they supposedly have a guy in place to lead the offense that is said to be more willing, capable, and able to get the most out of Dak Prescott and his skill set in new coordinator Kellen Moore.

With all that is seemingly going right during the offseason with the Dallas Cowboys, what could go wrong, thus preventing them from achieving the highest level of success this season? They, themselves, would be the only thing that could keep them from achieving these goals. Here is what that means.

Most of this current iteration of the Dallas Cowboys team has been together for at least three seasons, which has surely bred a sense of brotherhood or chemistry for lack of better terms.  What would quickly derail this team would be any semblance of unraveling or tearing within the fabric of this bond that they share.

One of the quickest ways to do so is for one of the members of said brotherhood to do something that seems like he is more focused on himself than the good of his brothers. With all of this talk surrounding extensions and new deals for multiple players, that could easily happen.
