The end zone has effectively been extended out to the 25 yard line where any punt within the 25 yard line will be brought out to the 25 yard line if the receiver signals fair catch or if the ball goes out of bounds or rolls within the 25 yard line.

Is it possible that returners won't make as much money as they once did since very few kick off returns ever go past the 25 yard line that were kicked into the end-zone.  Also, putting a guy like MO LANGI on the field as a returner may present more of a danger to the kickoff team than the receiving team, especially if a guy like Langi can catch the ball.
