There really wasn't anything wrong w the playcall. They bring Poyer down into the box on the TE a lot. There were a lot of things execution-wise that allowed that play to happen, but none of them are predictable. Like if Rousseau doesn't lose contain getting blocked by a TE the play goes for 1 yard. If Wallace is faster to recognize that his man is runblocking v Poyer and crashes down like he's supposed to instead of taking that last terrible step backward the play goes for 3 yards. If Milano doesn't slightly overrun his gap and is able to work back the play goes for 5 yards. If Poyer isn't held it goes for 7, if White isn't held it goes for 15, if Hyde takes a better angle it goes for 20.
