Looks like there were two players a few yards into the end zone, and a Pats player closing from the top. A few yards away so yes, not a "big" crowd, but any kind of a deflection and a number of Pats players could have made the pick.
It’s being reported that the Scout team won a practice scrimmage by finishing with Garrapalo hitting Boyce on this route against *Butler* on the same play this past week and Butler got chewed out for not recognizing it.
He learned.
