The shame is that Shafer's defensive approach and what they have been trying to do fits with a high tempo B12 style offense (this years results notwithstanding).
1. They have been working on getting a starting 22 on defense, playing almost like hockey line shifts.
2. Don't worry about total yards, worry about creating stops. When you really turn it up tempo on offense defense isn't about shut outs, it's about getting a couple of more stops than the other guy, situational defense, which Shafer has been able to do well most of the time here. Give up yards through the air, but be stout against the run on 1st and 2nd down and when you get a favorable down and distance create defensive wins through pressure. It would be a great marriage.
