According to this article....
Among the changes approved Wednesday:
— Raising of goal post uprights from 30 to 35 feet.
— The so-called "NaVorro Bowman Rule" (named for the San Francisco 49ers linebacker) which makes plays in which a loose ball is recovered subject to replay review. The alteration stems from Bowman's recovery of an apparent fumble by Seattle Seahawks receiver Jermaine Kearse that was instead blown dead by an official's whistle in January's NFC Championship Game with no review under previous rule.
— The game clock will no longer be stopped after a quarterback sack during the final two minutes of either half.
— A proposal by the New England Patriots to move the extra point attempt from the 2 to the 25-yard line was tabled. But the competition committee's recommendation to have a two-game preseason experiment with extra points snapped from the 20 is now in effect, adding some excitement to a virtually automatic play.
Extra points kicked from the 20 yard line? I kinda hope they make that permanent. Very interesting.
