RENTON, Wash. — One side has five Super Bowl rings, six most-valuable-player awards, 35 Pro Bowls and 62 postseason starts.
On the other, the boundless promise of what might be.
There are eight remaining quarterbacks in the NFL playoffs, and they fall neatly into two categories. It's the decorated superstars, each with at least 10 years' experience — Denver's Peyton Manning, New England's Tom Brady, New Orleans' Drew Brees and San Diego's Philip Rivers — and the skyrocketing next generation, each with three seasons or fewer and a combined eight playoff games — Indianapolis' Andrew Luck, Carolina's Cam Newton, San Francisco's Colin Kaepernick and Seattle's Russell Wilson.
There are contrasting styles and different situations among the quarterbacks, but the players also share a common thread.
"To be a really good quarterback you have to be clutch," Wilson said Wednesday. "You watch these quarterbacks the past few weeks, and these guys have been clutch."
Clutch, as in Rivers' guiding the Chargers to four consecutive December victories to sneak into the playoffs, then toppling heavily favored Cincinnati on the road in a wild-card game.
Clutch, as in Manning's setting NFL records with 5,477 yards passing and 55 touchdowns, two years after everyone — including Manning — thought his career might be over because of neck problems.
Clutch, as in Luck's digging his team out of a four-touchdown hole in a first-round game against Kansas City, at one point scooping up a ball that had been jarred loose at the goal line and, instead of falling to the ground to cover it up, leaping forward Superman-style for a touchdown.
"I saw that and thought, 'I wouldn't even have thought to do that,'" said retired quarterback Rich Gannon, a former NFL MVP. "I would have just jumped on it, whereas he just picked it up, jumped over a guy and leaned forward. Luck will lull you to sleep, because he has speed and strength and power if he wants to run."
That illustrates another line separating the two foursomes of remaining quarterbacks. With the occasional exception of Brees, the older ones are reluctant to tuck the ball and run, whereas the next generation will frequently make plays with their feet.
"There are coaches who have always felt that if you're going to be good, and you're going to win a big game, your quarterback has to run three or four times for a first down on third down," Hall of Fame coach John Madden said.
"Now that old-timer group, or whatever you call them, none of them are going to run three or four times for a first down. But the other group is going to. Brees, Brady, Manning … they're going to win it by throwing the ball. The other guys are going to win it by throwing it, and somewhere during the game getting a big run to keep drives going."
A look at the elite eight remaining quarterbacks:
The knack: Clear space for a fifth MVP award because Manning has had one of the greatest seasons in NFL history. His league records — 5,477 yards passing, 55 touchdown passes and five Broncos with at least 10 touchdowns.
The knock: Manning dominates the record books and has a Super Bowl ring, although his critics say he should have more. Despite his gaudy regular-season records, his teams are 9-11 in the playoffs with eight one-and-dones.
The knack: The Patriots lose their top five returning pass catchers, and voila, they're back in the playoffs. That's Brady. He directed five game-winning drives this season — including thrilling comebacks against New Orleans, Denver and Cleveland — and is reliably clutch in the playoffs, with a 17-7 postseason record.
The knock: It's like pointing out a door ding on a Ferrari, but Brady hasn't won a Super Bowl in nine years. Still, his three rings are three more than most NFL quarterbacks will ever own.
