Tough call here for sure. As crazy as it sounds, i think that Foles is maybe could be a "safer" pick in that he has a great matchup, but he is so green that i'm not sold that he can make the most of it. He's probably good for a mid range score.
Rivers is risky both because of his decision making this year and because Elvis and Von are going to be chompping at the bit to tear through SD's O-Line. I see Rivers as a potential boom or bust.
So make the decision on what you think you need to do agains your opponent this week. Even though he scares me a bit, i think i roll with the vet, rather than the inexperienced backup.
