Green Bay Packer Fans- question....?

I know the feeling. Last week the defense created turnovers against the Bears and then gave the ball back with an extra 15 yards because of stupid penalties. Today against the Lions, they held when they needed to, but they gave up WAY to many big third down conversions. I think part of the issue is that there are quite a few new guys playing in the secondary. Secondly, our tackling, at least today, was horrible. I think another part is the coaching. It's great to send crazy blitzes when they get to the quarterback, but it becomes a problem if blitzing allows lots of short, underneath completions that turn into big gains because there's no one there to make a tackle.
