I mean the whole "drop into coverage" thing is a bit overblown. MacDonald did that too. On two of the Chiefs sacks yesterday, Chris Jones dropped into coverage. And he's not a linebacker.
I'm not suggesting Orr's defense is awesome, but 32 NFL teams have determined Marcus Williams sucks ass at 29. So I'm not really interested on what he thinks about NFL defenses.
Jones yesterday wouldn't be the best example. He was on the field on 2 of the 3 sacks against Jackson and he rushed on both occasions. In fact, statistically, he dropped back into coverage 0 times. 7 times combined over the last 5 years, with 1 career catch allowed for -2 yards.
I get what you mean in general. That's not to say that it would be shocking for a player that isn't normally in coverage. If there's an overload blitz on the opposite side, or at least if the defender is feigning a rush. We did do that with Macdonald, to your point. I still remember being bewildered at giving up a critical 1st down against Pittsburgh wherein Clowney dropped to the sticks on a 3rd and 9 into the trips side, and we gave up the conversion. Weird then and weird now. But we did at least send 5, and we overloaded the opposite side, so somebody had to drop.
But this is from yesterday:
He's the WILL linebacker here, with a standard 4-man rush. And the closest intended defender against the X-receiver, with Nate Wiggins fanning out to cover the RB on the flat route. We dropped Odafe Oweh yesterday into the hook/curl to the trips side in a Tampa 2 yesterday with a 4-man rush. Which gave up a catch directly into his area, something I can't blame him for. We did at least manage to overload the Lions left side last week when we dropped Green into the middle of the field against Sam LaPorta, but we also again only sent 4 rushers and they were all picked up.
And these are exploited instantly. They're not even secondary reads where you're hoping they're not seen during the progression. The LaPorta throw was an instant read. Same with the one above to JuJu Smith-Schuster. So far, our edge rushers have given up 6 catches on 6 targets for 55 yards. We gave up 103 with Macdonald in 19 games, and that was at least to add wrinkles to an existing pass rush. Now, we're just doing them because it's a different look. Which would at least be somewhat understandable if we schemed them properly. But on most of them (if not all), we've sent an extra linebacker and dropped and edge player, so the blocking assignment is easier for the offensive line and the read is quicker for the quarterback. It's innovation over insulation. It's far from the chief concern with Zach Orr, but it does feel like a microcosm of the inexplicable calls we've seen.
