Maybe this camera angle will help, as this is the one I had referenced in a previous comment that showed a better view of the play.
The "immense" pressure was one d-lineman who was still 3 yards away. And the "deep support" couldn't be seen from the other camera angle because the other safety was at least 10 - 15 yards away.
I am not taking anything away from Will Brooks' interception, I'm simply trying to point out that if the QB had decided to throw to the other receiver he had an untouched path to the endzone.
