Recent history suggests that seeding and regular-season records don't count in the NFL playoffs.

There have been 18 wild-card upsets in the past decade, up from 12 in the decade before that. Six of the last eight Super Bowl winners had no bye on wild-card weekend.

Games can turn on single plays, and each of the league's 12 playoff teams made it this far on the strength of singular schemes on both sides of the ball.

Even the San Diego Chargers probably believe they can win the Super Bowl. They might even be right. As we outline here, each team does at least one thing to near perfection.

Seattle Seahawks (13-3)

There may be no tougher task in the NFL than finding holes in the Seahawks defense. Their lightning-quick line, which often features four ends at various positions, will make it so the quarterback has little time to execute. The defensive line allows the Seahawks to execute a defensive coordinator's dream: the ability to not worry about short run support or blitzing, allowing for some creative defensive back schemes.
