Sometime during the offseason I posted a few videos of him from college showing advanced hand use/pass rush technique (for a LB) where you see him effectively using rip and swim moves, even sometimes in conjunction with a chop or club.
That's advanced technique/pass rush plan that a good amount of pure DE's don't have coming into the league. To see him already using these moves, sometimes a series of them, in his 2nd NFL game is quite literally preposterous.
That's what Baldinger was talking about when he said "where did he learn this stuff?", because there are guys who take 2-3 years in the league before they're seamlessly stringing moves together like that.
