Lorenzo Neal was cut from the Chargers. He could be a huge boost to the running game, seeing as he could make valuable yardage for Marshawn. The Bills seem to prefer hybrid TEs who can come out of the back-field, but why not have formations with a pure fullback as well? It's not like H-Back was a huge/vital part of our offense last season. Getting a guy like Neal could have just as much of an impact as a guy like Wilford.
Speaking of Wilford, I wouldn't count on him coming to Buffalo. Likely the Dolphins are throwing everything they've got at him and he's lived in FL for his whole career. Buffalo may not be very enticing to him while he's down in South Beach.
