As there is quite a bit of game threading about Brady and his "decline" in the Game Goat thread, I'd thought it may be instructive to illustrate how the GOAT is doing this season.
At 14 games into the 2018 season, Brady is on pace for 586 attempts (5 more than last season, when he led the league), 386 completions (1 more than last season), and 4,457 yards (a whopping 120 yards less than last season).
His net yards per attempt of 7.23 is actually higher than last season and would be the 5th best season of his career. Looking at other stats:
Adjusted net yards per attempt: 7.37, middle of the pack career wise.
Rating: 97.6, right at his career average
QBR: 68.6 represents his 4th worst year, but that stat did not exist for his first 6 seasons. FWIW, it was 68.0 in 2015 when the Pats lost to Denver in the AFCCG.
His 9 interceptions loom large especially after this past game, which was his first red zone pick in 2 years. His INT percent of 1.8 is right at his career average, although it's the highest since the 2013 season. A couple of good (or bad) games in Weeks 16 or 17 could have an impact on this number.
That's all well and good, but how does he compare to other QB's in the league this year, especially with a number of even older QB's having career seasons in Rivers and Brees. The below deliberately ignores QB's that haven't played at least 12 of the 14 games.
Total yards: 5th, behind Mahomes, Roethlisberger, Ryan, and Goff.
Completions: 6th (behind Ben, Cousins, Ryan, Luck, and Mahomes)
Attempts: 7th (add Aaron Rodgers)
Completion Percentage: 16th, tied w/ Eli (ignoring Fitzpatrick and his 7 starts)
Net yards/attempt: 5th (ignoring Mullens and Fitzpatrick). Behind Rivers, Mahomes, Brees, Goff
Adj net yards/attempt: 6th Behind Rivers, Mahomes, Brees, Goff, and Ryan
Rating: 11th
QBR: 8th
Sack Percentage: 4th
Realistically, the QB's that are truly "better" than Brady this season have been:
Mahomes
Goff
Brees
QB's who arguably having better season than Brady:
Matt Ryan (quietely having another excellent season)
Rivers (maybe, or perhaps equal to Brady, as he's thrown 70 fewer passes this season)
Potentially equal to Brady:
Andrew Luck
Bottom line is that Brady is still right on the boundary of being a Top 5 QB this season, and clearly a Top 10. I'm sure there is some obscure "advanced" stat that questions this fact, but I still say the burden of proof is on those that dispute the above rankings.
