Just rewatched the 61-yard TD...
DJ was lined up on Pitta in the slot, Carter was lined up on the outside. Carter's man brushed DJ, allowing Pitta to gain separation on a 10-yard out pattern. Both DJ's and Carter's fault for missing the tackle.
I like Carter, and think he can correct his play, to do what he's supposed to do on the outside as a Nickel CB...but he just needs to get better.
DJ is going to have to get a lot tougher in coverage too.
