Observations from a brief All-22 study
It is the eyes, hips, and legs of the CB (#25?) when you watch the play.
Shaheed is running at a full sprint on a go. The corner's (#25?) eyes are on Carr the whole time and #24's assignment is the zone Kamara is in. #24 is also watching Carr's eyes but he is in his zone to defend so he's not leaving it.
If Carr throws to where Shaheed will be or leads Shaheed to the location with the throw, #25? would have to flip his hips, turn and find Shaheed, and run with an already full speed Shaheed. The best case scenario for #25 is that he has just enough quickness to recover and protect the inside, but he's toast if the ball goes where it is supposed to go between Shaheed and the sideline. Even if the Safety doesn't pickup Thomas and goes to Shaheed, the outside shoulder/area is still open.
This is just one of those things that made Brees special. He was able to identify these things and throw the ball before the receiver ever looked open. He'd see the body language and know with the play called, all he has to do is throw a catchable ball between Shaheed and the sidelines and its either first and goal inside the 5 or a touchdown.
I believe he only stops dropping back because he sees Carr turn to throw, he puts his foot in the ground and drives forward to go after the ball. You can see here Carr is midway through his throwing motion and Shaheed hasn’t gotten past him.
I still don’t understand what Carr saw pre-snap, both those receivers are essentially doubled and the DB’s were too far back to turn and run with the receivers before the ball gets thrown to Kamara (if that was the plan).
