FOXBORO -- The matchups for Sunday's AFC title game have been well-established: Great Offense vs. Great Defense. Vindication-seeking Defense vs. Vindication-seeking Quarterback.
Yet the oft-forgotten third element of the game, special teams, could also play a deciding role on Sunday.
The kicking game was an area of concern for the Ravens for much of the regular season. They ranked 31st in the NFL in yards allowed per kickoff return (29.2) and 24th in the league in yards allowed per punt return (11.9). They were also prone to giving up big plays when kicking it away. They tied Carolina, Oakland and Seattle with three kicks allowed for touchdowns (2 kickoff returns, 1 punt return).
When Baltimore received the ball, the results weren't much better as its special teamers had a tendency to put the ball on the ground. Kickoff return man David Reed fumbled three times during the regular season, including two on kickoff returns in a 22-17 Week 10 loss to the Seahawks.
Starting cornerback Ladarius Webb returned the first Texans kick in their Divisional Playoff game last week, but he fumbled that job away, too -- literally and figuratively. Though Webb continued to return punts for the Ravens, Tom Zbikowski received kicks for the remainder of last week's game.
With some uncertainty among Baltimore's return men, might the Patriots smell an opportunity for a game-changing play on special teams?
"We try to get the ball out every time if we could," New England special teams captain Matthew Slater said on Friday. "Those guys have had their problems but they're still a very tough unit. We have our work cut out for us, especially with coach John Harbaugh and his background in special teams. They'll be ready. I'm sure they'll be holding on to the ball, they'll make it tough on us."
The Patriots haven't been world-beaters returning kicks. They ranked 29th in the league in return yards per kickoff (21.4) and 16th in the league in punt returns (10.3). But if they can force a special teams turnover, it could change the entire tenor of a contest that may be kept close because of how the Ravens and Pats match up in the game's other phases.
One more trend worth keeping an eye on is how Ravens kicker Billy Cundiff kicks away from home. He has struggled kicking on the road this year, with all nine of his missed kicks coming away from Baltimore's M&T Bank Stadium. He's seen a significant drop-off in accuracy since last season, too, hitting on just 75.7 percent of his kicks after making a Pro Bowl-worthy 89.7 percent of his tries last season.
