'Buffalo lost half of their special teams core as Ron Brooks, Boobie Dixon and Chris Hogan are no longer on the roster. Their kickoff coverage lineup in last year’s season opener is down four players. The three aforementioned players and Bacarri Rambo, who is still a free agent. Add in the departure of returner Leodis McKelvin and Percy Harvin still undecided on where he’ll play this season, and it has left special teams coordinator Danny Crossman with the task of finding suitable replacements for a number of roles.'
