Todd Grantham has to go

Joe Woods is the DC in name only and Grantham is the D-Line coach. I don't know how familiar they are with coaching a 4-3 defense. All I know is before they came here, they were always associated with 3-4 defenses. Maybe they need to coach a defense that they're accustomed to running. This is definitely not working. To top it off it was DA that decided he wanted to go to a smaller defensive front 4 years ago and that's not working either. We're getting run though and run over and around. I keep banging the table for a real NT that can clog the middle and stuff the run. What makes no sense to me is you have 3 DC's in DA, Woods and Grantham and they can't figure out how to coach a defense REALLY!!!. I don't know maybe they're all trying to undermine each other and it's causing confusion with the players out on the field. But there is a problem somewhere between those 3. Somebody please explain it to me, because I just don't know anymore.
