This was an interesting idea for the NFL proposed in the Boston Globe a while back: the "time-in"

Here's the idea in short, by author Samuel Arbesman:

"If you’ve ever noticed that football games slow to a predictable crawl at the end of each half, the time-in is the rule for you. The idea is simple: When the clock is stopped, for whatever reason, a coach could call a “time-in”, and force the clock to start up again. Think of it as the antimatter version of the timeout."

He further suggests, because of the disruptive nature of this idea, coaches only be given one "time-in" to use per season. What do you guys think of this? I am not sure how I feel. And I certainly don't think our coach, Mr. Clock Mismanagement himself, needs anything else to mess up the clock. But I can't help but be intrigued at the thought of a post-season game coming down to a "time-in" and a hurried play. All hell could break loose, and that's kind of exciting...
