Last year's San Diego Chargers had a poor offensive line. In fact, according to Football Outsiders, only the Tampa Bay Buccaneers (who earned the #1 pick in this year's NFL Draft by being terrible last year) had a worse performance by their offensive line than Mike McCoy's guys.
While the team's top priority this offseason was to re-sign CB Brandon Flowers (done!), a close second and third items on that list were to re-sign King Dunlap (done!) and strengthen the offensive line around him...which is also now done.
Getting Philip Rivers some strong protection and providing more running lanes for the team's running backs are key to the success of this team over the next few seasons, and Tom Telesco has just one piece left before he can be totally confident in his starting five. Which piece? Well, that's almost irrelevant....
Mix and Match
Each of the following starting offensive lines are things that could happen....
LG (Mystery Player)
C Chris Watt
RG D.J. Fluker
RT (Mystery Player)
C (Mystery Player)
RG (Mystery Player)
LT (Mystery Player)
That last one is the least likely of the bunch, but I included it because I wanted to show that the Chargers could literally add another offensive lineman at any position and slide him in without forcing someone to play a position that they're ill-suited to play.
So, what now?
Who will the Mystery Player be?
Well, Chad Rinehart and Johnnie Troutman are still on the roster (for now) and have starting experience at the Guard spots. They could certainly fill one of those roles.
My guess is that Tom Telesco and his group of scouts will keep Troutman as a backup plan, and use a first or second-day draft pick on an interior lineman that will be given a chance to win the job opposite Fluker.
