I served what was ordered and there was plenty on full display to see the context past just the stat.
ETA not looking for a pissing match and I was going to say this earlier but was pressed for time. And what I was going to say is why the stat is interesting, why it deserved looking into. That's part of what I look at stats like this for, something to try and paint a picture of how this guy had success or lack thereof. I truly thought the context of the convo shined a light on this but sounds like not.
I had saw these stats a few days ago, found them when I was actually looking up info on Tyreek Hill. As
@rschroeder1 had indicated what caught my eye was that a primary slot possession WR was leading the league in a category otherwise dominated by WR's we generally see as "take the top off" kind of WR's. This struck me as odd a few days ago. I even looked up his average air yards per target and it was on the low side, around 9.5. So we got a guy who is getting almost 7.5 yards of cushion per target but averaging just 9.5 air yards target. This is not normal. I moved on from that at the time but it stuck in my head, something I meant to go back and revisit but my initial thought was that it had me lower on Kupp, that this was kind of painting a picture of a guy who was taking what the defense gave him.
Now when I read the stat saying he was the best WR in the league vs press coverage I recalled the cushion yards and thought now this interesting and for Kupp interesting in a really good way. This no longer painted a picture of a guy taking what the defense gave him to me. I'd like to get weekly info on this but why I said "I dont know it means" is because it made me wonder was he getting so much cushion because he was destroying teams who tried to press him? If so this paints a picture of a guy who is a matchup problem. You press him he beats you, you give him a fat cushion and he'll give you death by a million pin pricks.
This in a nutshell is why that stat mattered to me in the context of him being tops in the league vs press coverage and cushion and might help answer why a possession WR was sitting in a cushion category generally reserved for speed merchants.
