1 Dominate Chargers offensive line. This is where the Ravens need to cause problems because San Diego could be without center Nick Hardwick (ankle) and right guard Louis Vasquez (knee). The Ravens' Haloti Ngata and Kelly Gregg are licking their chops.
2 Secondary has to get in sync. If running back LaDainian Tomlinson is sidelined, quarterback Philip Rivers will be flinging the ball all over the field. That means the Ravens need to correct their lapses from the season opener.
3 Keep spreading the ball around. Ravens quarterback Joe Flacco threw at least two passes to seven receivers in Week 1. The Ravens can exploit last year's No. 31 pass defense if they keep the defenders guessing.
