Some good answers in this thread, but they’re spread around piecemeal. I’ll see if I can clarify a couple things for you.
Already answered; it’s more dangerous at high speed.
They described the block in the same text; after describing it, they named it with quotes.
It was Jeff feagles of the Giants that got, in the words of Monday night Countdown, JACKED UP. He punted, then started lazily jogging in the general direction of the returner, when he got obliterated by an viscious block. At the time, there was nothing he could have done to prevent it. Now, with this new rule change, he can opt to either just stand still or creep backwards in order to be officially off limits to such blocks. (He may actually do that, as opposed to the Giants kicker, Jay Feely, who loves to make tackles. He may be a short guy, but he clearly works out a lot and has delusions of being an actual football player.)
In all aspects of the game, players who go out of bounds cannot be the first player to touch the ball. This mostly applies to downing punts, but also bit the Panthers in the ass last week when they had touchdown passes negated twice because the receiver nicked the sideline while running the route. Twice!
The other type of “illegal touching” discussed in this thread is accurate, but does not apply to this rule you are asking about. This rule change means that if a player steps out of bounds, then downs the punt inside the five, in addition to the “take it there” or “rekick with 5 yard penatly” options, there is a new “touchback” option available to the receiving team. The reason for this change is stated as unfairly preventing deserved touchbacks, but the implementation has a different motivation: game speed. Since nobody would ever just take a ball inside their own 5, every instance of this scenario used to result in a rekick. Rekicks are very time-consuming, so the NFL put in this rule change to avoid the necessity. Many of the specials teams rules you ever see the NFL consider have the underlying motivation of speeding the game up. Bill Parcells discussed this topic at length in the preseason; his opinion is that he hates to see kicks removed from the game, as special teams are critical to success and a huge part of the game, but he conceded that he could see the value in keeping the game moving along.
You already answered this one correctly yourself.
anson2995, I’m almost positive that’s not the official rulebook. It’s the watered-down version they make available to the public. The actual, official rules are not public as far as I know. Also, regarding illegal touching:
That is not correct. A player who touches the endzone must establish both feet back in the field of play before he can be the first to touch the ball; as long as he does so, there is no problem. (Unlike out of bounds, which can’t be “washed away” by reestablishing the feet.)
