Yea its not black and white. I'd have run too. But it only makes their decision at the end slightly more difficult. Say the Bills ran 3 times for 5 yards and the put goes and is returned the same distance. The Texans then need 10 yards to get to where they kicked but throwing 10 yards and getting up to spike it is pretty doable with 15 seconds or so. Romo always say as long as you are throwing within 10 yards 12 seconds is the cut off for the complete pass in the middle and spike.
