During pre-season football, NFL teams rarely - if ever - allow their primary kick and punt return men to handle those duties, given the high risk of injury. For a team like the Buffalo Bills, who employ an abundance of talented return men, that may leave the question of who returns kicks and punts a bit murky heading into the regular season.
If the team's official depth chart is any indication, expect one major change from the 2010 season. Maybe.
Last year, C.J. Spiller was the team's primary kick returner, and was pretty average in that capacity save for one touchdown jaunt. He'll be joined back deep by free agent acquisition Brad Smith, who returned 50 kicks at 28.6 yards per return - with two touchdowns - for the New York Jets last season. However, with the NFL's kickoff rules leading to a lot more touchbacks this season, who returns kicks may quickly become irrelevant.
At punt returner, Roscoe Parrish remains one of the best in the game, and he'll continue to hold down that role. He'll be backed up by Spiller, as well.
