The NFL owners voted to move the PAT snap to the 15-yard line from the 2-yard line. Two point conversions will stay at the 2-yard line, and defenses now have the ability to score.
In years past, kickers have converted nearly 100% of the many PATs. With a more challenging kick, two point conversion attempts will likely increase in popularity. With the ability to score, defenses have a potentially game-changing opportunity every extra point.
