Gordon (knee) was clearly more comfortable in the Chargers' offense during the team's opening day of training camp, the San Diego Union-Tribune reports.

Gordon is coming off a disappointing, touchdown-less rookie year, but according to both he and quarterback Philip Rivers, appears more confident and comfortable with the Chargers' playbook going into his second season. Such development comes even after Gordon underwent microfracture surgery in January. Since then, Gordon trained this offseason with Vikings running back Adrian Peterson, an enlightening experience that also pushed him physically to prepare for the campaign. Now, with minimal thought about his knee, Gordon is well-prepared for an improved 2016 season as the lead back in San Diego's offense, which also figures to feature Danny Woodhead, particularly in the pass game.
