What does this even mean? How can you have more Value-Added Disruptions than regular disruptions? Oh, okay, I found it:
WHAT IS A DISRUPTION?
A disruption is a sack, tackle for loss, quarterback hit, pass defended, forced fumble, or interception.
WHAT IS VAD?
Value Added Disruption. Not all disruptions are equal. Some are more valuable than others. VAD is an attempt to gauge the value of each player’s disruptions.
Interception – 3.0
Sack – 1.5
Tackle for Loss – 1.25
Pass Defended – 1.0
Forced Fumble – 0.75
QB Hit – 0.75
How were those weights assigned? I'm guessing randomly, based on what the inventor felt like. A QB hit is worth as much as a forced fumble? A forced fumble is worth only half as much as a sack? I don't think this passes the smell test.
