Here's where Mac stands among 33 qualifiers for QB rate stats in 2022 (there were 31 qualifiers in 2021):

Completion percentage: 65.2%, 17th. (2021: 67.6%, 8th)

TD percentage: 2.7%, 31st. (4.2%, 13th)

INT percentage: 2.0%, 13th. (2.5%, 19th)

Yards/attempt: 6.8, 24th. (7.3%, 15th)

Adj Yards/attempt: 6.5, 25th.(7.0%, 16th)

Rating: 85.8, 25th. (92.5, 15th)

QBR: 32.5%, 31st. (50.9, 16th)

Sack percentage: 7.6%, 22nd. (5.1%, 10th)

In this case I think the numbers paint an accurate picture of the season Mac has had, and in comparison to last year. But it is also the case that he was terrible earlier in the season and has rebounded. Last 9 weeks:

Completion percentage: 65.2% (no change)

TD percentage: 3.0% (slight improvement, he'd be 29th if this was his full season number)

INT percentage: 0.7% (huge improvement - he's be best in league by a wide margin. Double it and he would be 6th in the league)

Yards/attempt: 6.5 (slight decline here, he'd be 28th)

Adj Yards/attempt: 6.8 (slight improvement here, he's be 18th)

Rating: 90.9 (he'd improve to 18th)

Sack percentage: 9.4% (decline, he'd be 32nd)

The statistical improvements are all primarily based on INT rate decline. I think the reduced yards/attempt and the higher sack rate reflect the disintigration of the OL and the shift to a lower risk short game.
