We man up, with a ton of work on blitzes. We'll get six defenders in a huddle, and race them to the line right before the snap. Sometimes one or two will delay. If they line up and the ball isn't getting snapped, they'll all start switching places, continually, until the ball is snapped. The O-Line has to be talking and pointing the whole time. Then at the snap we'll see how they actually block it.
The two biggest technique things we did was emphasize that once the hands go on, they stay on, and usually put the tackles in an up stance with a big stagger.
We've improved a ton the past few weeks.
