And the following free agents joined new teams: free safety Ed Reed (Houston Texans), linebackers Paul Kruger (Cleveland Browns) and Dannell Ellerbe (Miami Dolphins) and cornerback Cary Williams (Philadelphia Eagles).
In terms of reinforcements, the Ravens signed Pro Bowl outside linebacker Elvis Dumervil, free safety Michael Huff, defensive linemen Chris Canty and Marcus Spears, and they re-signed left offensive tackle Bryant McKinnie.
They also drafted a pair of All-American defensive players: Florida safety Matt Elam in the first round and Kansas State inside linebacker Arthur Brown in the second round.
Although the Ravens have undergone watershed changes after winning the Vince Lombardi trophy last season and qualifying for the playoffs for the past five seasons, coach John Harbaugh is upbeat about the state of the team.
"We are always as active as we can possible be to try to be as good as we can be," Harbaugh said following a recent organized team activity. "We’ve worked as hard as we can to put this team together over the last few months. Every single person in the building has done a great job, scouting side, coaching side and administration side, to try to put this group together, and we’ll continue to do that until we play the first game and beyond. I like where we are at, like the progress we have made. I’m excited about our team.”
