I probably start Foles.
As far as Locker V Kapernick: Locker is facing the cowboys, 3rd worse team against the pass last season, and their defense got worse. Kapernick is facing the Bears, who let Buffalo run all over them all day long. I figure Locker airs it out more, Kapernick keeps it on the ground.
And if Im going to be on Locker airing it out, I'm also betting on him connecting with Hunter, who led the Titans in targets last week.
Allen meanwhile is going to be squaring off against Seattle.
