Coach Jim Schwartz and GM Martin Mayhew have stressed the need for the 2012 later-round draft picks to fill multiple roles as they fight to make the roster. To that end, CBs Bill Bentley, Jonte Green, and Chris Greenwood, and LBs Ronnell and Travis Lewis have all participated in special teams’ drills during rookie minicamp. All of Detroit’s DB and LB draft picks have agreed their special teams play could be the determining factor in the race for the final roster spots.
