Rushing 2-3 men more often than I've ever seen a team do is what makes me think that they don't prioritize it. I don't think their pass rushing personel is particularly good (although Flowers looks pretty good) - but it doesn't really matter when you don't really rush guys. In a typical set on a passing down, if you rush 3, two guys get double teamed, and the 3rd gets a 1-on-1 but probably gets chipped by the TE or RB. Personnel doesn't make much of a difference there - you're just hoping somebody screws up an assignment or something.That's kind of a chicken and egg argument Stitch. Shipping out Chandler Jones may be interpreted by some as BB not prioritizing it.
The fact that they shipped out Jones and Collins, the fact that they've generally tried to find pass rushers on the scrap heap, or late in the draft, and that BB seems to prioritize reducing downside over increasing upside (passrush based defenses tend to be boom-or-bust) are all supporting evidence.
