'Defensive coordinators are going to play a safety over the top of Sammy Watkins a lot. But if Listenbee or Goodwin is a legitimate threat on the other side, opposing defensive coordinators will experience extreme pucker factor. I have to defend elite speed on both sides of the field? And I have to worry about LeSean McCoy’s elite speed? If the defense has to respect all three of those speed options, it will be as if the field is 70 yards wide and 120 yards long. It would give Buffalo a critical mass of elite speed.'
