The base defensive scheme isn't outdated, or if it is then at least 6 or 8 others are playing one that's outdated too, but it has to be played correctly to work. It wasn't. It's a one gap defense. Every lineman and every linebacker has one to cover and if he isn't in it there's a big old hole there even I could gain yardage through. A lack of talent, experience, and execution was what killed us not the 4-3 base defense.
