Chargers QB Justin Herbert intent on taking control of L.A. offense

— Preparing for his third NFL season, Justin Herbert says he’s focused on mastering the Chargers' offense this summer while not overlooking the little things that make him one of the NFL's elite quarterbacks.That means perfecting his footwork on mundane drills like drop backs with quarterbacks coach Shane Day and continuing to refine his throwing mechanics with 3DQB quarterback guru John Beck."A lot of it is still working on the drops and minor corrections here and there — footwork in the run game and just being smooth," Herbert said. Guys have tons of film to look back on from last year, and we’re farther ahead of where we thought we were going to be."Chargers center Corey Linsley recently compared Herbert to his former teammate in Green Bay."The biggest thing with Justin is you can tell he has that fire, perfectionist-type attitude, and Aaron has the same thing," Linsley said during an interview with SiriusXM NFL Radio. Last year, he tied for the NFL lead with Brady for most 300-yard passing games (nine) and rushed for the most yards by a quarterback in Chargers' history (302).Herbert already has developed into one of the best deep passers in the game.
