One of the main narratives following last season's Super Bowl was Tom Brady's undisputed claim as the NFL's GOAT. Even all-world receiver Jerry Rice conceded that title to Brady, who won his seventh Super Bowl and fifth Super Bowl MVP at age 43. While Brady's status as the GOAT can still be debated, his longevity and sustained excellence is truly peerless. 

While most everyone had already conceded the title of GOAT to Brady, Pro Football Reference did not officially give him the title ... that is, until the conclusion of the 2021 regular season. The website created a "Hall of Fame Monitor" in 2019 that was designed to estimate a player's chances at being inducted into the Pro Football Hall of Fame. Using approximate value, Pro Bowls, All-Pros, championships and other statistical milestones, the site created a point system to determine the pecking order at each position. 

Peyton Manning entered the 2021 season as the highest-ranked quarterback in league history with with 257.8 points. Brady was No. 2 with 250.94 points, followed by Brett Favre (179.96 points), Aaron Rodgers (174.76 points), Johnny Unitas (160.27 points), Joe Montana (154.17 points), Drew Brees (140.58 points), John Elway (138.66 points), Fran Tarkenton (116.55 points), and Dan Marino (117.02 points). Brady has since passed Manning with 259.32 points after leading the NFL this season with 5,316 yards and 43 touchdowns. 

Three members of the NFL's hallowed 2004 NFL Draft class are in the top 20 of PFF's Hall of Fame Monitor. Ben Roethlisberger, who is expected to make his retirement official at some point this offseason, finished his career ranked No. 13 on the list with 100.28 points. Roethlisberger is one spot behind Matt Ryan, who is the third-highest ranked active quarterback on the list behind Brady and Rodgers.

Philip Rivers, who retired following the Colts' playoff loss to Buffalo after the 2020 regular season, is 14th on Pro Football's QB Hall of Fame metric with 98.06 points. He's just behind Steve Young (111.65 points) and ahead of Barr Starr (97.93 points). 

Eli Manning, the first quarterback selected in the '04 Draft, is 20th on the list with 85.01 points. While his point tally is well short of the Hall of Fame average, Manning's ranking is higher than Hall of Famers Joe Namath (82.5 points), Bob Griese (73 points), Troy Aikman (64.28 points), and Jim Kelly (59.1 points), among others. He also has more points than current Seahawks quarterback Russell Wilson (78.79 points). 

While Brady has caught Manning, Rice's place atop the wide receiver food chain is pretty secure. Rice's 311.99 points are more than twice as many as the second-ranked receiver, Randy Moss (150.12 points). While Moss' 23 touchdown catches in 2007 remains a single-season record, Rice's three rings, 10 All-Pro selections (compared to four for Moss) and 13 Pro Bowls (Moss was a six-time Pro Bowler) put him in a class by himself.
