This was exactly my first thought. The answer is they don't trust the OL to block well enough in short yardage situations.
This is what sickens me, they don't trust the line in short yardage and goal to go situations, but is not like our passing game has propelled us to Saints, Pats, Broncos level. With all of these receiving threats and a so-called decent passing blockin OL, we still don't score efficiently enough with it for it to be our backbone.
The excuse that we pass so much cuz were trailing has been put to bed the last 2 games. They (poor run blockin/deficits) are excuses to pacify those that hate the over use of the pass game and to justify more passing. I can sense Murray is fed up with our soft run game mentality and I hope his comments become a national story to put the offensive play calling on notice.
First and goal at the 5 means with a 3.whatever avg we score on two plays (take that avg freaks)! We're a mediocre passing team cuz we always shoot ourselves in the foot with a penalty or Romo INT and the 8-8s prove it!
RUN THE BALL AND DEVELOP SOME OFFENSIVE MENTAL TOUGHNESS
