The Pick: Lane Johnson (OT), Oklahoma
FA Activity: San Diego added just two offensive linemen to its roster with the additions of King Dunlap (OT) from the Philadelphia Eagles and Chad Rinehart (OG) of the Buffalo Bills.
The massive 6'9", 330-pound Dunlap started 12 games at left tackle for the Eagles in 2012—the most in his five-year career. Dunlap isn't an instant starter from day one, but he will definitely challenge to play either side of the line.
Rinehart is a sixth-year pro who played just seven games last season after suffering an ankle injury that placed him on the injured reserve list. The 27-year-old is reunited with his former position coach from Buffalo in Joe D'Allesandris. Rinehart's chances of landing a starting role are much greater with the departure of Louis Vasquez to Denver.
Round 1 Analysis: In Round 1, the needs remain the same for the Chargers. Even though Jared Gaither (OT) and Jeromey Clary (OT) still hold roster spots with the team, San Diego is in desperate need of an upgrade at both positions.
Offensive guard is also a dire situation. With Vasquez gone and Tyronne Green (OG) still unsigned, the Chargers have no current starters left on the roster to man the inside of the O-line.
Oklahoma's Lane Johnson has been penciled in at No. 11 on numerous mock drafts, but I wouldn't be surprised to see a guard prospect taken here—Alabama's Chance Warmack or North Carolina's Johnathan Cooper.
