Kansas City Chiefs quarterback Patrick Mahomes trails just one NFL QB in terms of cumulative grade since the start of the 21st century, and that Hall of Fame signal-caller is Peyton Manning, not Tom Brady.<\/p>\n
In a document shared with Heavy, Pro Football Network ranked the top 25 quarterbacks of the 21st century, but there was a catch. This ranking went strictly by QB+ grade.<\/p>\n
Pro Football Network described QB+ as \u201ca formula that assigns a score and letter grade to each quarterback\u2019s individual performance. The metric blends stats like success rates when pressured, third-down conversion rate, and pocket production. The added wrinkle? Quantifying \u2018clutch.\u2019 We used timeliness-based stats to account for score and situation.\u201d<\/p>\n
After PFN compiled all that data,\u00a0Mahomes\u00a0placed No. 2 overall, with\u00a0Manning\u00a0as the 21st-century champion \u2014 so far.<\/p>\n
Mahomes is still playing, so his cumulative grade could still rise and fall, while retired quarterbacks like Manning and\u00a0Brady\u2019s\u00a0grades (ranked sixth highest) will remain static. They could move up or down the list, too, but only if current\u00a0NFL QBs either fall below them or surpass them.<\/p>\n
\u201cMahomes is only 29, but he already has a case as a top-three quarterback of all time,\u201d PFN wrote, noting the Chiefs superstar\u2019s Super Bowl titles, MVP awards and \u201c17-4 playoff record.\u201d<\/em><\/p>\n <\/p>\n Pro Football Network detailed Peyton Manning\u2019s grade, too, as well as Tom Brady\u2019s, and\u00a0you can find the full list via this link\u00a0(including a few unexpected inclusions). For Manning, they wrote:<\/p>\n No quarterback in NFL history has won more MVPs than Peyton Manning, who claimed the honor five times over his 18-year career. Known as the \u2018Sheriff\u2019 for his command at the line of scrimmage, Manning lived up to the hype after being selected No. 1 overall in the 1998 NFL Draft.<\/p>\n Manning revolutionized the position with elite accuracy, pre-snap reads, and relentless preparation. He led some of the league\u2019s most dangerous offenses, including the 2013\u00a0Denver Broncos, where he set single-season records for both passing touchdowns (55) and yards (5,477). He finished his career with 71,940 passing yards and 539 touchdowns, ranking third all time in both categories.<\/p>\n Manning\u2019s advanced metrics are elite, posting a near-perfect 99.9 QB+ score. His +0.23 career EPA per dropback is the best of any quarterback in the 21st century, and in close games, his +0.26 EPA\/DB ranks second only to Patrick Mahomes.<\/p>\n Manning\u2019s playoff r\u00e9sum\u00e9 isn\u2019t as pristine \u2014 14-13 record with an 87.4 passer rating \u2014 but he proved he could win when it mattered. He became the first starting quarterback to win Super Bowls with two different franchises. Two titles, seven first-team All-Pro honors, and 14 Pro Bowls later, Manning now has a bust in Canton.<\/em><\/p><\/blockquote>\n One more former Chiefs quarterback made this elite top-25 NFL quarterback ranking:\u00a088-game KC starter\u00a0Trent Green.<\/p>\n \u201cTrent Green\u2019s sample size isn\u2019t as large as most other retired quarterbacks on this list,\u201d PFN noted. \u201cHe made 113 starts and finished with a 56-57 record, having missed nearly two full seasons early on. Green also entered the league at age 27, and by the time QB+ was introduced, he was already 30.\u201d<\/em><\/p>\n \u201cGreen finished his 11-year career with 28,475 passing yards, 162 touchdowns, and 114 interceptions,\u201d the site went on. \u201cOutside of a league-leading 5.5% touchdown rate in 2002, he didn\u2019t top any major statistical categories \u2014 unless you count leading the NFL in picks in 2001 (24).<\/p>\n \u201cGreen ended with a +0.14 EPA per dropback, with his most notable metrics being 7.3 net yards per pass attempt and a +0.37 EPA per rush on 109 designed runs.\u201d<\/em><\/p>\n Mahomes and Green were the only 21st-century Chiefs QBs to make this list, although Rich Gannon (who played for Kansas City prior to the turn of the century\u00a0from 1995 through 1998) graded out 15th for his late-career resurgence with the then-Oakland Raiders.<\/p>\n","protected":false},"excerpt":{"rendered":" Kansas City Chiefs quarterback Patrick Mahomes trails just one NFL QB in terms of cumulative grade since the start of the 21st century, and that Hall of… <\/p>\n","protected":false},"author":2,"featured_media":71917,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5],"tags":[],"class_list":["post-71916","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-nfl"],"yoast_head":"\nWhy Peyton Manning Is Currently Graded Higher Than Patrick Mahomes & Tom Brady in NFL Quarterback Ranking<\/h2>\n
