Ravens keys to victory
1. Angry birds: Outside linebackers Terrell Suggs and Paul Kruger must contain (and punish) Colin Kaepernick — particularly on third down, when he does some of his best magical work.
2. Bird calls: Keep the plays simple. Asking Joe Flacco to carry the offense is a mistake. Go with a healthy dose of Ray Rice and let the quarterback be the complementary piece.
3. Bird brains: There are a lot of fiery Ravens who play with an edge, and sometimes that edge is costly. Be smart and avoid the late hits, the helmet-to-helmet hits, and the whining.
