In 2018, Brady ranked 9th in attempts, 8th in completions, 18th in completion %, 13th in completion % among QB's with over 3500 yards passing, 7th in passing yards, 13th in INT% (11th if you remove Flacco and Wentz), 13th in yards/attempt, 11th in adjusted yards/attempt, 14th in yards/catch, 12th in rating (11th if you remove Ryan Fitzpatrick's 7 game season), and 9th in QBR.
However, most of the higher ranked QB's threw far fewer passes. His overall rating was 6th among the 12 QB's with >550 pass attempts, and his QBR 5th. So his place in the top 10 was actually fairly solid in 2018.
Brady's numbers were indeed down across the board in 2019, but he was 4th in attempts, with only Goff, Winston, and Matt Ryan being asked to hoist the rock more often than Brady.
