OT: This position has been near the top of the Lions' list of needs for several years. Aging LT Jeff Backus only has so many years left.
CB: Another spot that the Lions have struggled to find playmakers. They added Jacob Lacey in free agency but let Eric Wright walk. The remaining pieces are extremely underwhelming.
RB: In theory, the Lions' backfield trio of Jahvid Best, Mikel Leshoure and Kevin Smith would give them one of the deepest groups in the league. Instead, all three are injury risks and Leshoure has had off-field trouble.
