Unfortunately, I don’t see how it could have been a miscommunication. Zay was holding out his arm and running to the left, and Allen just threw so far behind him that Zay had to try and change directions.
Zay was running away from coverage, so there was no reason at all for Allen to try and lead Zay the other way.
It was just a bad miss by Allen. (IMO anyway, with the limited info we have)
