ravens dismantling defense

This years off season is ridiculous for the Baltimore Ravens as they are losing many of there defensive stars from Ed reed to Houston , Paul Kruger to Cleveland, pollard to Tennessee and Ray Lewis to retirement. I think that the Ravens did a terrible job on trying to Keep there defensive stars, they only focused on quarterback Joe Flacco and the offensive stars. in my perspective i think Baltimore is gonna try to be like the New England Patriots from 2 years ago being high power on Defense and very poor on there defense.
