text:  No, it's just a completely different job. A lineman's hand is on the ground. His focus is real tight. He's looking at the ball on a penetrating defense, or he's looking at the nose of the man lined up across from him on a reading defense. That's all he sees. Where a linebacker's up, he's off the ball. He's on the balls of his feet. He's got to go either way. He's got to go backwards, forwards, sideways. It was a huge move.
