To start with, I really like the idea behind this entire play. From a condensed formation, everyone fans out, attacking the edges of the defense. We've got a chip on the left side of the line to help with Jadeveon Clowney [90] before heading out to the flat, but Jonnu Smith [81] - the right TE - is different. It starts off looking like a block, but ends up being a delayed release to the middle.
With the routes attacking the edge, the middle is completely open. We've also got some man coverage on the back end, which leads to a lot of people having their backs turned to the play.
