‘Duke Preston was part of Buffalo’s top wedge group on kickoff return. He’s the early favorite to replace the departed Justin Bannan who ran in between Daimon Shelton and Ryan Neufeld on the wedge that runs in front of McGee. Other wedge candidates include Robert Royal, Tim Anderson, Justin Geisinger, Lauvale Sape, Brad Cieslak and Ryan Denney. The fullback role on kickoff return that has been held primarily by London Fletcher the past two seasons may be handed off to someone else this fall in an effort to keep Fletcher from getting nicked up.’
