Like DeAngelo WIlliams said, the key is to get 8 first downs (80 yrds) as opposed to trying for one 80 yrd run. That shows the difference between a selfish player (wanting the glory for himself) and a team player (wanting the team to be successful).
A team that can sustain drives, kill the clock, and score....will help the defense dominate a game by keeping them fresh (off the field). DD shows he can help sustain drives. The OC play-calling last year killed drives!
Have a strong Offensive game plan, mixed with a solid defense...and this team is going places. Get that stud DE (Mario) and the defense will be strong. Get RB, and the offense may not necessarily be strong. A defense can shut-down one player......most offenses must change plans if a player is dominating the OL/Offense (like a Mario Williams would). That is called getting the offense out of their gameplan.
