Frank Ammirante pushed back against the "doom-and-gloom" around Najee Harris’ freak Fourth-of-July eye injury. Harris returned to drills Tuesday, and Ammirante believes that trajectory gives him "a good chance" to be active for Week 1, where he is expected to share backfield duties with Omarion Hampton. With many drafters fading him on injury fear, Ammirante labeled Harris a late-summer discount for anyone comfortable with a committee role in the Chargers offense.
