Irresistible force vs. Immovable object

Broncos: Mind-blowing stats

1 Big-game experience: The Broncos are 2-4 in their previous Super Bowl appearances. But Denver won its past two: 31-24 over Green Bay in XXXII and 34-19 over Atlanta in XXXIII.

2 Indicator of success: Bronco fans are hoping their team leads at halftime of Super Bowl XLVIII. Denver is now 14-1 all time in the postseason when leading at halftime, including 5-0 in AFC title games. The one loss? Super Bowl XXI, when the Broncos led the Giants 10-9 at halftime before losing 39-20.

3 Defensive turnaround: The Denver defense was maligned during the first 14 games, giving up 26.6 points and 371.5 yards per game. But in the past four games, including two in the postseason, the Broncos have turned stingy, allowing just 15 points and 268.5 yards per game.

Seahawks: Mind-blowing stats

1 Beast Mode unleashed: Marshawn Lynch has rushed for more than 100 yards in four of six career playoff games, including 100-plus efforts against both the Saints and 49ers in postseason victories this season.

2 Seattle strength: The Seahawks finished the regular season first in total and scoring defense, the 25th time a team has led both categories since 1940. That team has reached the title game 14 times and won the title game nine times (most recently the 2008 Steelers).

3 Carroll’s touch: Seattle’s defense has shown remarkable progression since Pete Carroll took over as head coach. The unit ranked 27th overall in 2010, improved to ninth in 2011, fourth in 2012 and first in 2013.
