Jolly Good Fellow
Vad's low YPC is a product of the system. If someone is gonna have a negative play it's gonna be the QB or the AB, but the ABs have an easier chance to make that yardage back. If you're a pocket style QB, it's a lot easier to consistently pick up 5-15 yards on a QB scramble when the defense isn't expecting it compared to the designed run of an option QB. If you take out Vad's negative yards, he averages 3.74 yards/attempt rather than 2.8. DS only had 1 negative yard. I'm not saying Murray is slow, but he's by far not as mobile as Russell Wilson.
