Getting to know the Patriots' playoff opponent, the Baltimore Ravens, with 10 quick-hit thoughts:
1. They posted a 9-7 regular-season record, finishing second in the AFC North.
2. Run defense is a strength, as they ranked fifth in the NFL in fewest rushing yards allowed per game (93.3), and first in fewest average yards allowed per carry (3.4).
3. On the other side of the ball, they are more of a running team than they were Oct. 4 when they visited the Patriots. Led by running back Ray Rice and a physical offensive line, they ranked fifth in the NFL in rushing yards per game (137.5) and fourth in average yards per carry (4.7).
4. Officials called 115 accepted penalties against them. Only two teams had more.
5. They have produced more offense in the second half -- 230 of their 391 points have come in the third and fourth quarters.
6. Turnovers are a big part of their success. Their plus-10 turnover differential ranked fourth in the NFL (32 takeaways, 22 giveaways).
7. Red-zone defense is a strength, where they finished the season ranked fourth -- opponents were held to 18 touchdowns on 43 trips (41.9 percent success rate).
8. They ranked first in the NFL on kickoff returns.
9. They made an in-season change at kicker, with Billy Cundiff replacing Steven Hauschka. Cundiff is 12 of 17 on field goals since joining the Ravens.
