It is not the fact that he is blocking his man to the ground that impresses me. It is the fact that even though dominating seems easy to him, he still seems hell-bent on planting each and every player he gets his hands on. That takes a lot of energy. The very last highlight is him chasing a defensive back around; the DB has no intention of trying to make a tackle, he is just trying to get away from Miller. And Miller doesn't quit. Eventually the whistle blows, and you can almost see the frustration in Miller's body language that one "got away."
Nasty. I predict he will be competing with the Paulsens and Kallenberger for a starting guard next year (unless Kallenberger is good enough to kick Jackson inside).
