Allen does that all the time and backs out of it to disguise the defense. If he brought all 8, or 7, or even 6 you have a point. But I don't think he did that.
Beyond all the rest of it, even if that was a bad call, he called a very good game overall holding them to 15 points and containing Hurts for most of the game. They still need to clean up the run D and stop giving up big plays, but that's nitpicking when they gave up 10, 19, and 15 points so far this year.
