How much of that is because of the talent on the field in GB, though? If you have Rodgers at QB, I don't believe it's a stretch of logic to be a pass happy team. -EK 
Possibly.  If I was a coach I would pass more if I had a QB like Rodgers, Brady or Peyton. I would run more if I had an RB like LT or AP.  If my RB and QB was equally talented (or untalented) I would be more balanced.  The Dolphins don't have a superstar at either position, a balanced approach makes the most sense.  Of course if you constantly playing from behind, you need to throw more.  If you have a comfortable lead -- run more.
