The Redskins have signed NT Ron Brace. Brace was released by the New England Patriots on 12/29/2012. He was a second round pick of the Pats in 2009.

Here is an explanation of Brace's release from the Pats.

But Brace, who grew up in Massachusetts and attended Boston College, never emerged as he or the team hoped. It is a reminder that size is a good place to start along the d-line, but more needs to come together (e.g. technique, footwork) in a player's development.

As a rookie, Brace worked as a backup nose tackle in the 3-4 alignment behind Wilfork, who was in the final year of his contract. Initially, Brace was viewed as insurance in the event Wilfork departed as a free agent.

But by the end of the year, the Patriots knew that Brace, who played 4-3 defensive tackle at BC, wasn’t a fit on the nose (he seemed to play too high at times). That tilted some leverage in favor of Wilfork at the negotiating table as he signed a five-year, $40 million deal in 2010.

In his second season, Brace was used at left defensive end in the 3-4, and it was the spot in which he made his most significant contributions, although he never carved out a full-time role.
Redskins seem to be giving chances to draft busts. Earlier, the Redskins signed former second rounder Phillip Merling.
