In recent campaigns, there's been a question at the LT position for the San Diego Chargers -- they thought they'd secured a long-term solution with a six-year extension for Marcus McNeill in 2010, but he retired in 2012 after a string of injuries -- and that question persisted into the 2013 offseason. With training camp underway, the battle there is an area of focus.
