The Kyle Shanahan score-score-and-score-some-more philosophy starts with some central tenets: collect fast, athletic players and find space for them to operate; then run the ball to assert dominance, control the clock and keep defenses honest, opening more space. Shanahan loves to run the outside zone. He majors on play-action passes, and he wants to make those concepts look similar before changing which players go where and how wide they split out.
He also knows specifically what he wants at each position. Take offensive linemen, for instance—Shanahan prefers lighter ones who are more athletic, because he asks them to move laterally more than most coaches.
