A look at today's Seattle-Green Bay and Jacksonville-New England matchups by the numbers.
Here is a look at Saturday's playoff matchups by the numbers:
SEATTLE AT GREEN BAY
The game should be a battle of the offenses – the Packers are rated second in the league in total offense (21st rushing, 2nd passing), while the Seahawks are rated ninth overall (20th rushing, 8th passing).
No team has allowed more first downs via penalty than the Packers and it's not even close – Green Bay has allowed 44 first downs as a result of defensive penalties, while the next highest total was 28.
The Packers were fifth in the league with 49 touchdowns scored and tied for second with just 31 TDs allowed.
The Seahawks had better hope to get off to a strong start, because the Packers have outscored their opponents 221-133 in the second half this year.
Brett Favre was sacked just 19 times this year, the third lowest sack total in the league.
Despite having just 188 rushing attempts, Ryan Grant fell just 44 yards short of 1,000 yards for the season and averaged 5.1 yards a carry.
Despite leading the team with 82 receptions and 1,048 yards, Donald Driver had just two TD catches – which tied him for fifth on the team. Greg Jennings led the way with 12 TDs and Donald Lee added six.
Four Packers – Driver, Jennings, Lee and James Jones – had 47 or more receptions this year.
The Packers allowed less than six yards per punt return this year – third among NFL teams in 2007. That could be tested, since Nate Burleson finished fourth in the NFL with a 11.3-yard punt return average and trailed only Devin Hester in the NFC.
Favre completed two-thirds of his pass attempts this year and finished with a passer rating of 95.7.
The Seahawks were just 3-5 on the road, including losses to the Cardinals, Browns, Panthers and Falcons.
Seattle played just two playoff teams during the regular season – beating the Bucs in the opener and losing to the Steelers in Week 5. The Packers played four playoff teams and went 3-1 against them.
The Seahawks converted on just 35 percent of their third-down plays, the worst percentage of any playoff team and sixth-worst among all teams.
The Packers may not want to try to convert on a fourth-down attempt. Opposing teams went on fourth down 17 times against the Seahawks this year and made good on just five of them.
The Seahawks outscored their opponents in each quarter this year, but were especially impressive in the third quarter, where they held a 73-39 scoring edge.
Of their 349 yards of offense per game, only 101 of that came on the ground, while 248 came through the air.
Shaun Alexander is clearly no longer a dominant running back in the NFL. After "hitting the wall" last season and missing significant time to injury, Alexander had just 716 yards rushing on 207 carries – an average of just 3.5 yards a rush. He had just 88 yards more than teammate Maurice Morris, but did it with 67 more rushing attempts.
The Seahawks got a pair of 100-yard rushing games in the first three games of the season, but didn't have a 100-yard rushing day in the final 13 games. The Packers were rated last in rushing prior to Grant taking over and he finished the season with five 100-yard games in half a season of work.
Former Viking Burleson led the Seahawks with 11 touchdowns – a team-best nine receiving TDs, a punt return for a touchdown and a kickoff return for a score.
Seattle's Marcus Truffant finished third in the NFL with seven interceptions.
JACKSONVILLE AT NEW ENGLAND
The Patriots had 115 more first downs (393) than their opponents (278).
Kicker Steven Gostkowski scored 137 points – 63 on field goals and 74 on extra points and didn't win his team's scoring title. That went to Randy Moss with 138 points on 23 touchdowns.
The Patriots aren't just all offense. While the team had the top-rated offense (1st passing, 13th rushing), it also had the fourth-rated defense (10th rushing, 6th passing). The Jaguars had the seventh-rated offense (2nd rushing, 17th passing) and the 12th-ranked defense (11th rushing, 15th passing).
The Patriots' scoring disparity was massive this year. They outscored opponents 134-41 in the first quarter, 333-137 in the first half and 256-137 in the second half.
While Maroney didn't have a huge season offensively, he averaged 4.5 yards a carry – finishing with 835 yards on 185 carries.
Six Patriots players had 36 or more receptions, led by Welker (112) and Moss (98).
Moss has been involved in the two highest-scoring offenses in NFL history – the 2007 Patriots and the 1998 Vikings.
If the Patriots are vulnerable anywhere, it would be on the ground, where they allowed 4.4 yards per rushing attempt.
Patriots opponents attempted just 14 field goals all season – the least of any team in the league.
The Patriots converted 48.2 percent of their third-down attempts, while allowing opponents to convert on just 33.7 percent.
The Patriots punted just 44 times – an average of less than three a game.
The Patriots had more than twice as many sacks (47) than their opponents (21) and were led by Mike Vrabel with 12.5.
Tom Brady completed 69 percent of his passes for 4,806 yards and a league record 50 touchdowns, while throwing just eight interceptions.
Brady's passer rating of 117.2 was the second highest rating in league history – trailing only the 121.1 total of Peyton Manning set in 2004 when he established the single-season TD record with 49.
The Jaguars didn't lose back-to-back games all season.
The Jags averaged almost 150 yards rushing per game.
The Jaguars do most of their damage early and late – outscoring opponents 92-47 in the first quarter and 135-86 in the fourth.
While the Jaguars offense isn't given a lot of credit for their success, the team scored 50 touchdowns (fourth best in the league) – with 18 rushing touchdowns (fourth in the league) and 28 passing TDs (tied for ninth best).
Fred Taylor came on strong late with five 100-yard games and an average of 5.4 yards a carry.
Taylor and Jones-Drew were another example of the two-headed backfield that has come into vogue in the NFL, combining for 1,970 yards on 390 carries – an average of more than five yards per carry.
Nobody on the Jaguars had more than 45 receptions, but five players had 37 catches or more.
Jacksonville kickers had just 24 field goal attempts this season – only the Dolphins had less.
While Brady gets all the attention, Jaguars quarterback David Garrard was third in the league with a passer rating of 102.2. He, Brady and Ben Roethlisberger of the Steelers were the only QBs with a passer rating of 100.0 or better.
