Different qb steps in Utah run game

Tiger cat is correct on this. It is the veer option and the zone read option that you are talking about. On the veer you will see the qb actually push the los and on the zone he will just open and pivot. As for the rb, on the zone read it looks more like a draw play with his footwork being to shuffle over, and on the veer look he is taught to drop step with his inside foot 45 deg. Hope this helped you.
