According to the Union-Tribune San Diego, the Chargers have “no immediate plans” to add another running back. The Chargers lost backup Mike Tolbert in free agency this offseason and did not add another veteran back to replace him. Right now they just have Curtis Brinkley and his 32 career carries, 7th round rookie Edwin Baker, and fullback Le’Ron McClain behind lead back Ryan Mathews.
Norv Turner has talked Ryan Mathews up as a feature back extensively this offseason. Turner’s offenses typically feature 300 carry type feature backs and in his 3rd year after going 12th overall in 2010, it appears Mathews has Turner’s trust to be that type of back. Mathews has a career 4.7 YPC and Chargers’ running backs caught 104 passes and scored 16 times last year on a down year for the San Diego offense so there’s definite fantasy upside with Mathews, who Turner thinks can lead the league in rushing.
The report did leave the door open for the Chargers to add another running back closer to Training Camp by saying they have no “immediate plans,” but any running back they sign will likely be a pure backup to Mathews. Any running back signing would be a vote of no confidence on Brinkley, Baker, and McClain as pure backups rather than a vote of no confidence on Mathews as a feature back, who seems to have all the confidence of the coaching staff. Mathews is currently my #3 fantasy back behind Arian Foster and LeSean McCoy.
