Jake Locker (shoulder) practiced again on Friday and will start Sunday's game at San Diego. Coach Mike Munchak never wavered on Locker's availability for Week 2 and said Friday that his quarterback finished the practice week on "a high note," taking the usual full complement of reps. We like Locker as a high-upside QB2 against a banged-up Chargers pass defense. Locker was mostly sharp in the opener, going 23-of-32 for 229 yards, one touchdown, and one interception.
