Week 1 vs Arizona
After a huge start to 2013, Philip Rivers threw for over 300 yards just once after Week 9. That was thanks to the emergence of RB Ryan Mathews who caught fire before getting banged up late in the year. The plan for the Chargers all along was to run the ball, but early on Rivers had three 400-plus yard passing games in the first five weeks.
The Bolts are again primed to run the ball with Mathews, Donald Brown and Danny Woodhead but Rivers does have some passing weapons to work with. However, coming in to Week 1, Rivers is a middle of the road QB2 ranked 15th against the Cards defense that was 19th allowing points to QBs.
Outside of Week 2 at home vs. Seattle, Rivers' schedule is very favorable Weeks 3-6 but using him as a QB2 is probably the best bet.
