N.F.L. Playoffs: Who Is Going to Get the Super Bowl

Three of the quarterbacks in Sunday’s N.F.L. conference championship games have Super Bowl rings. The fourth is a leading candidate for this season’s Most Valuable Player Award.

Advantage: no one in particular.

The conference championships won’t be decided by the quarterbacks — Pittsburgh’s Ben Roethlisberger or New England’s Tom Brady in the A.F.C., or by Green Bay’s Aaron Rodgers or Atlanta’s Matt Ryan in the N.F.C.

The final round of Super Bowl LI qualifying will come down to the doings, or the undoing, of the 42 other starters on offense and defense. Spoils to the best supporting casts.

Here is a look at Sunday’s matchups and who we think will win them. All times Eastern.

Green Bay’s Aaron Rodgers has thrown 21 touchdown passes and one interception during an eight-game winning streak. Atlanta’s Matt Ryan has thrown 18 touchdown passes and three interceptions in his last eight games.

The tiebreaker goes to the better pass rush, which is more an exercise in theory than an actual practice with these two bottom-floor defenses.

Rodgers seems to do his best work when he is on the lam from the pocket, faking left and right until he can make a deep throw on the move; so flushing him outside the hash marks only worsens the situation.

The Falcons — starting with the N.F.L. sacks leader, linebacker Vic Beasley Jr. — must trap Rodgers from the outside and either force him to throw the ball before he wishes or take him down before he escapes to his improvisational zone.

Blitzing isn’t always the brightest idea, given Rodgers’s rapid release. But consider one weak link: Running back Ty Montgomery, a converted wide receiver who too often gives blitzing defenders the bullfighter’s wave and lets them race right by him.

If the front seven can’t slow down Rodgers, no one will. The Falcons ranked 28th in passing yards allowed per game, and season-ending injuries to two starters have forced them to use an undrafted rookie, Brian Poole, in nickel packages.

Atlanta’s task should be easier since Green Bay’s Jordy Nelson, who had 1,257 receiving yards in the regular season, has been sidelined by fractured ribs. But then, Rodgers threw passes of 25-plus yards to five other receivers in last week’s 34-31 victory at Dallas.
