Five rules changes, an extensive crackdown on on-field taunting and abusive language and a two-game preseason experiment that will move extra-point attempts from the 2-yard line to the 20 (effectively a 38-yard try) will bring a new look to the 2014 NFL season.

Representatives from all 32 teams unanimously approved three rules changes Wednesday adding to the two adjustments ratified Tuesday as the three-day owners meetings concluded.

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.

More significant than raising the uprights was a concerted move to raise the standard of player conduct on the field.

"In the past, taunting/sportsmanship was in the back of the book under points of emphasis. It is now a front-of-the-book issue." competition committee member and St. Louis Rams coach Jeff Fisher said. "We want to put it back in the back of the book."

The emphatic crackdown on taunting will result in more 15-yard penalties for unsportsmanlike conduct because Fisher said the league is trying to set the standard for college football and other youth levels of the game.
