If it's not recognition on the combo route in the endzone, it's an issue with technique on the nine by Quick. I don't believe his problem was at the top of the route so much as he played the snap about as poorly as you can.
If you're playing the receiver eye-to-eye to start the play and then allow him a free release to the outside, even a marginal passer is going to complete that over the top. There was zero disruption early in the pattern which leads us into the "when you're even, I'm leavin" dynamic.
And I gotta say, that chicken wing by Quick didn't seem like much by NFL standards. Then again, when you have a target on your back the size of Claiborne's, it might seem like all forces are working against you.
Obviously, the pass rush is anemic and puts the coverage at a distinct disadvantage. Still, this cornerback looks to be the daisy of most o-coords and QBs to the point passers will rarely need to progress through their reads.
I just hope this is something the player and staff are addressing and working through. If not, Scandrick won't be the only name passing Mo on the depth chart. And if Claiborne hits the field with this sort of thing is his bag Sunday night, Drew Brees will absolutely break him.
