Even IF 0 was over the top help, 8 Ivey had the flats!Roman needs to get the sky view of the play. 0 was the over the top help, he guessed, and was on the other side of the field. That play happened because 0 ****ed up.
My guess would be Harvey had the flats and jumped the in-cutting route. Ivey had deep 3rd, 24 deep middle, TS2 the other deep 1/3 with JW0 rotating to the other flat due to motion making that the strong side of the field.
