Although there haven't been any official announcements, it appears new Detroit coach Jim Schwartz has lined up most of his coaching staff.
David Birkett of the Oakland Press reports that former Tampa Bay assistant George Yarno will be the Lions' offensive line coach. Meanwhile, holdover Shawn Jefferson (receivers) and Sam Gash (running backs) are expected to be retained in their current positions. Former offensive coordinator Jim Colletto, who was demoted to offensive line coach earlier this month, is not expected to be retained.
Previously, it's been reported that former Denver defensive coordinator Bob Slowik will coach defensive backs and former Tennessee assistant Matt Burke will handle linebackers. That leaves the defensive line as the only job that is publicly unaccounted for.
