I noticed this yesterday on the all 22 review. This play was the equivalent of someone walking around a corner to catch a ball that is already in the air and coming in hot.
As I've said before he still has to catch it, but Miller made this a much harder catch than it appeared to be in real time. That ball was on him very quickly.
Zay is going to be fine. I wouldn't be surprised to see him get a few targets early on Sunday.
