The Baltimore Ravens strengthened their defense and special teams by signing a two-year deal with cornerback Corey Graham, a three-year contract with Brendon Ayanbadejo, and a one-year deal with safety Sean Considine.
The team also announced it had re-signed starting inside linebacker Jameel McClain for three years.
The 26-year-old McClain had 81 tackles, one sack, an interception, five pass deflections and two fumble recoveries.
Graham, a Pro Bowl special teamer for the Chicago Bears, visited the Detroit Lions and Minnesota Vikings. Graham intercepted a career-high three passes with one forced fumble last season and should play a role in Baltimore's secondary.
"I definitely see myself making an impact," Graham said. "I study, I care about the way I play and I figure if I'm going to be doing special teams, I want to be the best special teams player in the league."
In five seasons, Graham has 180 tackles, four interceptions and two forced fumbles.
"I never really planned on going anywhere," Ayanbadejo said. "I figured it would get done. I just didn't know exactly when. Now that it's here and done, it's kind of anticlimactic."
