Williams Christian Jones (Rookie) Khaseem Greene In one of the most wide-open competitions of training camp, only Lance Briggs is guaranteed a spot heading into the Week 1 of the regular season. After years of having Brian Urlacher hold down the middle of the field at the middle linebacker position, the 2013 Bears saw what life was like without him. Veteran D.J. Williams took over the middle linebacker job and played well until an injury ended his season in Week 6. He is expected to reclaim that job again this offseason. One of the more interesting competitions will be at strong-side linebacker with converted defensive end Shea McClellin competing with second-year man Jon Bostic for the starting job. McClellin and Bostic appear to be locks at the position, which leaves Khaseem Greene, Christian Jones, Jerry Franklin, DeDe Lattimore, Conor O'Neill and Jordan Senn to compete for what will likely only be two remaining spots. Despite his struggles in his rookie season, Greene will likely make the roster. While Franklin and Senn both offer experience on special teams, the potential of undrafted free agent Christian Jones should be enough for him to make the roster. A once projected mid-round pick, Jones reportedly failed a drug test at the NFL combine in February, according to Fox Sports' Jay Glazer (h/t Orlando Sentinel), which likely caused him to go undrafted. He has the flexibility to play all three linebacker positions but is best suited on the strong side. As long as he can prove his worth on special teams, it is unlikely that the team would be willing to lose him.
