Shou and Co., please forget the promising appearance of the 4.1 rushing average. It means absolutely nothing in this case. Here's why:
I believe other teams are getting 3-4 yards a pop and an occasional 10-30. That's typical for a decent rushing game. Their 4 yard average is constructive.
1. It earns them balance, which is needed to loosen up tight coverage of receivers, pulling the defense in closer to the line of scrimmage, giving the passing game a better chance of success.
2. It gives them a real chance to run out the clock as halves close. If you can be fairly certain of 3.0 each rushing attempt, all you have to do is run it 3 times and get lucky on one of them for that extra yard. Even if you don't quite make it, you have the option of going for it on 4th and short, and likely making it. You've also run minutes of precious time off the clock or forced your opponent to take defensive time outs. Not ideal for them!
3. If the opposing defense tries to stack the box against a rush, especially on an obvious rushing play like 4th and inches, there's no better time to attempt a play action pass! (approaching 85% chance of success, I'd wager).
This is what the Dolphins of the '70s did all the time.
On the other hand, our current running game is so sporadic that it cannot be counted on earning a 3rd and 1 conversion, for heaven's sake. Are we even above 30% for the year? I've be surprised if we are. That is NOT constructive. I can see why Sherman thinks he must pass as much as he does, even when we really, really need a first or to run down the clock dependably.
