At his best, Ravens PK Billy Cundiff is accurate on field goals and exceptional on kickoffs. But he has struggled on field goals recently, missing three of his last five attempts, all from 41 yards or closer. A left calf injury has been a concern since Week 14, and the Ravens added Shayne Graham as insurance as Cundiff heals. Cundiff, who won PFW's Golden Toe Award as the NFL's outstanding kicker/punter in 2010, has missed nine field goals this season, compared to just three from a season ago, though five of his 2011 misses have been from 50-plus yards. Graham, while accurate on field goals, doesn't hit his kickoffs as far as Cundiff, who has forced touchbacks on 42-of-71 attempts this season. When they have had to cover kickoffs this season, the Ravens have not fared well, with opponents averaging 30.9 yards.
