standard to you is a waste to me. At least most of the time with Preston. Don't see Zadarius doing it. Normally the edge makes 4. Or you should actually have someone who can cover.
Preston is actual a decent cover man for a 3-4 OLB or 4-3 SOLB.
And rushing 4 as a base call is universal in all schemes. You don't want to blitz. Other coverages are possible, but the basic goal is to rush 4, play 5 cover men in Man-to-Man and keep both safeties deep. Cover 4, 3, and 2 also require 7 men in coverage.
In base, the 3 down linemen and one of the edge players typically rush. Z is far worse in coverage, so he drops less, Preston does it more. 12-15% strikes me as very reasonable for an OLB. (I would however like to find the source of these stats. Possible he drops more or less than typical.)
In sub-packages, it's harder to decide who should rush, who should drop. On Nickel downs, I'd expect him to drop sometimes. In Dime and lighter, I'd expect him to rush more.
I also would like to point out Present being the widest cover man in some calls certainly looks weird, but isn't actually odd in practice.
If Preston has a tight end or back responsibility and then that man shifts, motions, or just initially lines up out wide, who should cover him? A corner, just because the fullback lines up as flanker? And then what, have Preston take the WR that's lined up as a flexed tight end? Sometimes the best option isn't the "Most-Good," but the "Least Crappy."
