I don't think so...typically on a RPO, the OL will wait a beat before going downfield, but you can see all of the OL sit back in a pass block set. I think JT is right that someone just blew an assignment. If I had to guess, I think it's on Etienne which doesn't surprise me given he's a rook.
edit: watching the end of the video from the QB view, it also looks like a good designed look by Miami by showing 7 but dropping the LDE back and rotating the rush to overload the right side, think that essentially left Icky and Lewis to block one guy and left Moton and Tremble 1 on 1 with their own men and no one to account for the right most rusher
