Five numbers behind Russell Wilson's historic season

In 2015, Seattle Seahawks quarterback Russell Wilson set new franchise records in completion percentage (68.1), yards (4,024) and passing touchdowns (34).

He put together one of the most remarkable stretches in NFL history as the Seahawks won six of their last seven games to earn a playoff berth.

With help from ESPN Stats & Information, below are five numbers behind Wilson's 2015 regular season.

110.1 -- Wilson's passer rating, which was tops in the league for the entire season. When you shrink the numbers down to the seven-game stretch from Week 11 to Week 17, his rating was 132.8. It was during this time that the Seahawks lost tight end Jimmy Graham and running back Thomas Rawls. They were already playing without Marshawn Lynch, and Sunday against the Cardinals, the Seahawks had backups in the game at left tackle and right guard. But Wilson completed 71 percent of his passes, averaged 8.78 yards per attempt and threw 24 touchdowns against one interception during the seven-game period. The Seahawks won six of those games. With the season on the line, no quarterback in the NFL was better.

118.6 -- Wilson's passer rating on throws from inside the pocket. Not only was that the top mark among this year's group, but no quarterback in the past three seasons has posted a higher number. Wilson completed 72.8 percent of his passes, averaged 8.75 yards per attempt and tossed 31 touchdowns against seven interceptions when he stayed in the pocket. Since Week 11, the numbers are 77.8 percent, 9.90 YPA, 22 touchdowns and one interception. That equates to a passer rating of 145.1. Regardless of what happens in the playoffs, this will be one of the most important things to come out of the 2015 season for the Seahawks. When Wilson has time to sit back in the pocket, he can pick defenses apart. He's shown that ability in the past, but never at such a high level, and it's made the Seahawks extremely tough to defend. If opponents want to try to stay disciplined with their pass rushes and not allow Wilson to scramble, he's perfectly content to hang tight, survey the field and deliver on-target all game long.

1 -- The number of quarterbacks in NFL history that have thrown for at least 4,000 yards and 30 touchdowns, while also running for 500 or more yards. Wilson is alone in this club, according to ESPN Stats & Information. The rushing yards tend to get overlooked at this point, but only Carolina's Cam Newton and Buffalo's Tyrod Taylor had more among this year's quarterbacks. Wilson can beat teams in a number of ways: the quick passing game, bootlegs, shot plays and running it. Most importantly, he's been smart about when to use his legs. Of his 553 rushing yards, 466 were before contact. Wilson has shown he knows when to take off, when to get down, when to get out of bounds and when to fight for extra yardage. He has not missed a game or even a practice in four NFL seasons due to injury.

80.4 -- Wilson's completion percentage when targeting wide receiver Doug Baldwin. According to ESPN Stats & Information, no other quarterback/wide receiver combination has posted a higher number in the last 10 years. Since Week 10, when Wilson has targeted Baldwin, he's completed 47 of 59 passes (79.7 percent) for 724 yards (12.27 YPA), 12 touchdowns and one interception. That equates to a passer rating of 150.3. Baldwin has gotten more opportunities and made the most of them. He became the only player in the last 15 years to post a 1,000-yard season while catching at least 80 percent of his targets. Overall, Baldwin finished with 78 catches for 1,069 yards and 14 touchdowns (tied for tops in the NFL).

79.0 -- Wilson's completion percentage on third down since Week 11. That was the top mark in the league over that span, as was his 144.7 passer rating. Seahawks coaches are obsessed with third down -- both on offense and defense. In the first 10 weeks, Wilson was completing 56.5 percent of his third-down passes (21st), and the Seahawks were struggling to extend drives. But down the stretch, the protection has been better, Wilson has had more options, and his decision-making has been outstanding. One key has been how quickly he's been getting rid of the ball on third down. Before Week 11, Wilson was taking 2.77 seconds before passing, fourth-longest. But since then, that number is down to 2.36, fourth-fastest. Overall, the Seahawks converted 46.5 percent of their third downs, fourth-best in the NFL and their top mark since Pete Carroll became the head coach. Since Week 11, they've converted 59.4 percent, tops in the league.
