When you have your secondary playing 10-15 yds off the ball, bad things happen. Trufant has cover skills, yet can't tackle. Same for quinton richardson. He's gone. Lets hope new d coaches recruit speed and athletes who know how to fundamentally tackle. Lots of missed tackles in the past 3 years. Probably the number one reason Holt and crew are gone. Pressure on the qb has been lacking also. Offensively, with core group back, they will hold there own. Defensively, cleaning the slate and starting over, won't/can't hurt any worse.
