I thought Dee showed much improvement over his rookie season. The PFF stat of his league leading 23 QB pressures in December looks accurate when you rewatch the film.
He got pressure on Carr here several times and forced some early throws and dumpoffs.
He's got 5.5 sacks in only 600ish snaps (half a seasons equivalent). He can get in the backfield on speed and effort alone, and while he did show a bull rush and spin move in this game, those moves need to be perfected and utilized along with better hand usage.
I think the floor for him should be 7 sacks. He can do that with the amount of time he'll play. He just needs to push through and do finish plays like the one in NE that he missed and cost us.
Here's all of his snaps from Oakland:
