The Kubiak zone run game is different, as they rely on backside cut blocks in a way that other zone teams don't. Those backside cut blocks give our DTs fits, as they are getting their knees taken out from behind while they are following the flow of the play. That's a very different approach and one that's tough for a team to adopt over a 2-week period, as it relies on letting those slower players run free toward the play and making a very committal, almost diving block to enable the cutback. If you don't practice that a lot, you're liable to miss those blocks, and the play gets blown-up in the backfield.
