The Ravens have signed CB Frank Walker to a 2-year, $3.5 million dollar contract.  He played in 12 games last season for the Packers and he made 17 tackles and defensed a pass.  Walker has now played in 53 games in his NFL career and he has made 84 tackles, defensed 10 passes, forced a fumble and he’s picked off 5 passes including one that he returned for a TD.  Walker is a special teams ace and he could help the Ravens out as a nickel or dime back so this was a decent signing for them.
