Ravens add depth with Marcus Spears

The Baltimore Ravens signed Dallas Cowboys defensive end Marcus Spears to a two-year, $3.55 million contract, which continues a free-agent trend for Baltimore to upgrade the defensive line.

The Ravens made it a priority earlier this week when they signed former New York Giants defensive end Chris Canty, and they addressed it again Friday with another 30-something lineman from the NFC East.

Don't expect Spears to start. He was a backup last season for the Cowboys. And don't expect him to make an impact in the pass rush. Spears has two sacks in his past three seasons.

What Spears brings is the ability to stop the run and a charismatic personality to the locker room. Spears, 30, was a 2005 first-round pick by Dallas who was cut Thursday because he was scheduled to make $2 million in 2013 and he didn't fit in the Cowboys' new 4-3 defense.

After signing two veteran defensive linemen, the Ravens should turn their attention to adding an inside linebacker and safety. Those are major needs after Baltimore lost inside linebacker Dannell Ellerbe to Miami and released safety Bernard Pollard. The Ravens could also lose Ed Reed, who is currently a free agent.
