The Dallas Cowboys are working hard to shore up their receiving corp with the loss of Laurent Robinson and the mercurial nature of their starting wideouts. Much talk in the press and among fans has centered on bringing in a veteran receiver.

But Johnson's release doesn't help the Cowboys because they could sign him to the squad. That would be an unmitigated disaster. No, his release after a domestic assault charge sends yet another strong message to Dez Bryant that off field behavior can cost you your job.

Johnson has gone from talented receiver and showman to cautionary tale. And Bryant can't get enough cautionary tales to keep him on the straight and narrow. Bryant has all the tools to become one of the top receivers in the league.

The only thing that can hold Bryant back is Bryant. Which is why Johnson's release is so valuable to the Cowboys. By keeping Bryant's impulsiveness in check and keeping him focused, Dallas' receiving corp will benefit tremendously. 

Once the Cowboys are getting a full four quarters of production from Bryant, things will open up for the other receivers. Opposing teams can't double cover Austin and Bryant both. And don't forget about Witten or new targets James Hanna and Andre Holmes.

The Dallas offense has been kept from its potential, not by the Giants or Eagles or Redskins secondaries. None of those units has what it takes to shut down Bryant. No, the Dallas offense has been limited by Bryant himself. He has taken himself out of games. By getting overly emotional, by being out of shape and by not knowing the playbook.

If reports from camp are to be believed, Bryant is finally getting it. He's understanding the offense, he's in better shape, and he's abusing every corner they send his way.

Johnson's release comes at the perfect time to remind Bryant that when he returns to Dallas he needs to avoid domestic drama and focus on the career that he is privileged to have.
