Great view of the play though I do not totally agree with the break down.
At least he did mention that CJ also looked left.
The play design didn't help the QB.
Look at how the slot receiver ran his route.
The way he stemmed to the outside helped drawing the safety closer to where the pass was going to be.
It was just a bad play design or execution.
You need to draw up a play where one receiver can lure the safety away from the other receiver.
That was either a bad play design or a poor execution by the receiver(s).
When you see a safety in position to defend two receivers, you know something is not going right for the offense.
