I think the Chargers simply have too much firepower on offense in the passing game. Between big, fast receivers in Keenan Allen, Stevie Johnson, and Malcolm Floyd to go with tight ends Ladarius Green and Antonio Gates, Phillip Rivers should have his pick of who is more open on Sunday.
The Ravens won't be bothered much by a rushing attack that has been one of the worst in the league, causing this to turn into a shootout fast. One that Joe Flacco seems to have regressed in this season.
