McCoy does fall down, but Chip Kelly does not design pass plays with only one option. Down the field, Riley Cooper and Zach Ertz are running a very tight-fitting crossing route. Cooper is being held from the minute he makes his break almost across both hash marks. If he hadn't been, he'd have run free into a wide open space and Foles – who is clearly looking for him in those middle frames – would have had an easy pitch and catch.
