Arian Foster running out of bounds

Reading failure on my part apparently, but yeah that clock rule has been in place for a while. The college game actually implemented a similar rule in their game after the NFL except its the last 2 minutes of each half. The most head scratching clock rule was when NCAA had the clock start after change of possessions so you had teams having to run their offense on the field like a fire drill if they were out of timeouts and were trying to make a late drive to win the game. One of the most bizarre things I've ever seen.
