He seems to have lost his mojo in the Green Bay game in 2021, not with the knee injury.
There are a lot of conflating factors, but since the ACL tear, he's recovered to a bit better than his pre-injury state, but nowhere near his pre-GB level. Leaving out his rookie season when he was just learning how to play in the NFL:
2020-GB 2021 (23 gms): 15-8, 69.0%, 2.53 TD:Int, 1.9 pass TD/gm, 7.8 y/a, 100.7 rating, 1.9 sacks/gm, 7.7 rushes for 41 y/gm
GB '21-NE '22 (18 gms): 5-13, 66.0%, 1.75 TD:Int, 1.2 pass TD/gm, 6.4 y/a, 86.9 rating, 2.2 sacks/gm, 6.2 rushes for 40 y/gm
2023 - 2025 (30 gms): 13-17, 67.8%, 1.95 TD:Int, 1.2 pass TD/gm, 6.8 y/a, 91.6 rating, 2.1 sacks/gm, 5 rushes for 33 y/gm
Maybe that GB game, ending his 7-0 streak, showed the league something about how to defend him??
