Lions running back Jahvid Best has not been limited during the team's voluntary offseason program. Jim Schwartz said Saturday that Best is "doing the same things everybody else is doing." Best is coming back from a season-ending concussion. "I saw (Best) in the meeting room, but I haven't seen him working out," Martin Mayhew said of Best, who 11 games last season because of a concussion sustained against the 49ers. "From what I understand, he's been doing everything, as far as conditioning and working out with everybody."
