Breaking down the Cowboys' latest roster moves

As the Dallas Cowboys' leading tackler, linebacker Sean Lee, was lost for the season this week, the team was left with another hole to fill in their lineup.

The signings of safety Charlie Peprah and linebacker Ernie Sims are the Cowboys' most-recent attempts to further strengthen their second-ranked total defense in the league, and SB Nation's Blogging the Boys provided its analysis of the moves.

On Peprah, the seven-year pro out of Alabama, Blogging the Boys said, "A knee injury cost him his offseason with the Packers and ultimately led to his release," adding that, "The Cowboys think his knee is healed up fine, and if it is, they could have a solid veteran to take up the spot vacated by Barry Church and the spot which Danny McCray has been struggling with."

In Sims, the seven-year veteran from Florida State, however, Dallas has a "totally different situation," according to the post. "On the surface, this does not look like a player who will help the Cowboys on defense.

"Let's hope they brought him in only for special teams," the Cowboys blogger concluded.
